Definitions
- alkaline compositions are known in the art based upon the use of one or a mixture of alkaline reacting substances which are principally inorganic alkali metal hydroxides and salts of relatively weak acids.
- the alkalinity serves the function of cleaning, emulsifying, saponifying, peptizing, descaling, derusting, paint and/ or wax stripping and the like.
- Nonionic surface active agents have been employed for this purpose, being substantially insensitive to heavy metals or alkaline earth metal ions and having excellent wetting, dispersing and/ or emulsifying properties.
- non-ionic agents discolor badly when mixed with such alkaline reacting substances in dry form such as powders, shaped products and the like.
- the liquid nonionic agents dedust dry alkali compositions at first, but lose this power after about two Weeks or so whereby such mixes thereafter dust badly.
- the nonionic agents exhibit very little solubility in highly alkaline solutions, thereby greatly limiting their usefulness.
- the sulfate esters of such nonionic surface active agents do not have any substantially higher solubility in alkaline solutions.
- Alkylaryl sulfonates have also been commonly employed in dry alkaline compositions, and while they do not discolor as do the nonionic surface active agents, they are substantially insoluble in the presence of large concentrations of calcium or aluminum ions normally present in many cleaning operations, such as diary bottle washing and the like. Further, they do not have any dedusting action.

- the above defined reaction product of P 0 with a nonionic surface active agent may be prepared by the process described and claimed in the copending applications of Nunn and Hesse, Serial No. 852,188, filed November 12, 1959, and of Nunn, Serial No. 856,367, filed December 1, 1959, now respectively U.S. Patents 3,004,- 056 and 3,004,057.
- the reaction between the P 0 and the nonionic surface active agent is conducted under substantially anhydrous conditions and at a temperature below about C.
- the reaction is carried out by adding the P 0 gradually, with vigorous agitation to the nonionic surface active agent in liquid form.
- the reaction is exothermic and cooling is in some cases necessary to keep the temperature below 110 C., since discolored and darkened products tend to be produced above this temperature.
- the reaction proceeds continu- 3,1 same ously during the addition of the P and is preferably followed by maintenance of the reaction mixture at ambient temperatures up to 110 C. for an additional period of time after completion of such addition to allow for complete solution of the P 0 and reaction with the nonionic surface active agent.
- the product produced by the above described reaction is not definitely known in view of the recognized tendency of the P 0 to form complex products and polymers in such reactions with hydroxylic compounds.
- the product will usually contain about to 45% of the secondary phosphate ester of the nonionic agent, to 80% of the primary phosphate ester, 0 to of unreacted nonionic agent, and small amounts of unidentified by-products.
- a phosphorus-containing compound selected from the group consisting of hypophosphorous acid, salts of hypophosphorous acid, phosphorous acid, and salts and esters of phosphorous acid, preferably sodium hypophosphite or hydrophosphorous acid, as described in said Nunn application, lighter colored or substantially colorless reaction products are obtained.

As such compounds con-- taining a reactive hydrogen atom there may be mentioned alcohols, phenols, thiols, primary and secondary amines, and carboxylic and sulfonic acids and the r amides.
- These compounds may obviously contain more than one reactive hydrogen atom, i.e. more than one hydroxy, mercapto, amino, amido, carboxylic, sulfonic or sulfonamido group, each such group in the compound being reactive with the alkylene oxide in suitable proportions.
- the amount of alky lene oxide or equivalent condensed with the reactive hydrogen-containing compound i.e. the length of the po-lyoxyalkylene chain, will depend primarily upon the particular compound with which it is condensed. As a convenient rule of thumb, amount of alkylene oxide or equivalent should be employed which will result in a condensation product containing about 20 to 95% by weight of combined alkylcne oxide. However, the optimum amount of alkylene oxide for attainment of the desired hydrophobic-hydrophilic balance may be readily determined in any panticular case by preliminary test and routine experimentation.
- reaction between the reactive-hydrogen-containing organic compound and the alkylene oxide in the production of the above described nonionic surface active agents is Well known in the art, being preferably carried out at elevated temperatures and pressures and catalyzed by quaternary hydroxides, amines, acids and/or coordinating type compounds although strong alkaline catalysts such as KOH or NaOH and the like are preferred because of fewer by-products formed and the more easily controlled reaction conditions.
- the reaction is substantially quantitative, although it will be understood that the product of this reaction between the alkylene oxide, preferably ethylene oxide, and the organic reactive hydrogen-containing compound will be a mixture of polyoxyalkylene derivatives of varying oxyalkylene chain length, the average of which substantially corresponds to the amount of alkylene oxide reactant. Such product will of course always contain an average of at least one hydroxy group (in a terminal C H OH group) per molecule.

Description
United States Patent 3,168,473 HIGHLY ALKALINE SURFACE ACTIVE *COMPGSHEUNS Andrew Stel'cilr, Easton, Pan, and Fred E. Woodward, Plainficld, NJL, assignors to General Aniline dz Film Corporation, New York, N.Y., a corporation of Delaware No Drawing. Filed July 2%, 196% Ser. No. 45,799 8 (Iiaims. ill. 252 135) This invention relates to highly alkaline surface active compositions, and more particularly to such compositions containing an organic surface active agent.
A great number of highly alkaline compositions are known in the art based upon the use of one or a mixture of alkaline reacting substances which are principally inorganic alkali metal hydroxides and salts of relatively weak acids. In these compositions, the alkalinity serves the function of cleaning, emulsifying, saponifying, peptizing, descaling, derusting, paint and/ or wax stripping and the like.
It has also been customary to include in such composition one or more synthetic organic surface active agents to provide a Wetting, dispersing, foaming or similar function and to contribute to the primary function of the alkaline reacting substance. Nonionic surface active agents have been employed for this purpose, being substantially insensitive to heavy metals or alkaline earth metal ions and having excellent wetting, dispersing and/ or emulsifying properties. However, such non-ionic agents discolor badly when mixed with such alkaline reacting substances in dry form such as powders, shaped products and the like. The liquid nonionic agents dedust dry alkali compositions at first, but lose this power after about two Weeks or so whereby such mixes thereafter dust badly. In addition, the nonionic agents exhibit very little solubility in highly alkaline solutions, thereby greatly limiting their usefulness. The sulfate esters of such nonionic surface active agents do not have any substantially higher solubility in alkaline solutions.
Alkylaryl sulfonates have also been commonly employed in dry alkaline compositions, and while they do not discolor as do the nonionic surface active agents, they are substantially insoluble in the presence of large concentrations of calcium or aluminum ions normally present in many cleaning operations, such as diary bottle washing and the like. Further, they do not have any dedusting action.
It is an object of this invention to provide a hghly alkaline surface acve composition in dry or liquid form which will not be subject to the above disadvantages attributable to the previously employed synthetic organic surface active agents. Other objects and advantages will appear as the description proceeds.
The attainment of the above objects is made possible by this invention, which broadly comprises the provision of a highly alkaline surface active composition containing the reaction product of P 0 with a nonionic surface active agent having the molecular configuration of a condensation product of at least one mole of ethylene oxide, and up to an amount sufficient to provide said agent with about 95% by weight of combined ethylene oxide, with one mole of a compound containing about 6 to 150 carbon atoms and at least 1 reactive hydrogen atom in a ratio of 1 mole of P 0 for each 2 to 4.5 hydroxy groups in said nonionic agent, and an amount of an alkaline reacting inorganic alkali metal substance suiiicient to yield with said reaction product an aqueous solution having a pH of more than about 12 when the combined concentration of said reaction product and said alkali metal substance in the solution is about 0.3% by weight.
The compositions of this invention have been found to be highly effective and improved with respect to one or more of the above mentioned deficiencies and disad- 3,168,478 Fatented Feb. 2, 1965 vantages. They may be employed for the production ofhomogeneous liquid concentrates containing relatively high proportions of inorganic alkali metal substance and the defined surface active reaction product. When provided in dry or particulate form, the compositions of this invention have improved resistance to dusting, discoloration and/ or decomposition of the components of the composition. Further, these compositions have highly desirable low or controlled foaming properties, relatively high wetting, dispersing, emulsifying, and/or detergency properties, and reduced corrosive action on metal, vitreous, ceramic, and other surfaces with which they may come in contact.
As the alkaline reacting substance to be employed in the present compositions, the alkali metal (sodium, potassium) hydroxides and silicates are preferred although other sodium or potassium salts may be employed such as the phosphates, carbonates, boratcs, and the like. Instead of or in addition to these strong alkali metal salts, there may also be employed relatively Weaker salts such as the sodium or potassium polyphosphates, sulfides, cyanides, acetates and the like, the basic requirement being that the alkali metal substance, whether a single compound or a mixture of compounds, be employed in an amount sufficient to supply a concentration of alkali metal ion effective to yield a pH of more than about 12 when the compositions of this invention are dissolved in aqueous solution in a concentration of 0.3%. i
As specific examples of inorganic alkali metal substances, there may be mentioned sodium and potassium hydroxide, phosphate, carbonate, sesquicarbonate, bicarbonate, tetraborate, perborate, sufide, cyanide, acetate, orthosilicate, metasilicate, polyphosphates, and the like. Those alkali metal silicates are preferred having a mole ratio of M O:Si0 of at least about 0.721 and up to 2:1 or the like, where M means Na or K. These orthoand metasilicates are highly effective strong alkaline reacting substances.
The alkali metal polyphosphates are well know in the art and may also be referred to as condensed phosphates or molecularly dehydrated phosphates. In general, these polyphosphates have an analytical ratio of alkali metal oxide to P 0 of less than 3:1, such ratio usually falling within the range of about 1:2 to 5:3. These polyphosphates are available as alkali metal pyrophosphates, metaphosphates, and polyphosphates in monomeric or polymeric form such as the triphosphates, tetraphosphates, hexametaphosphates, decaphosphates and the like. As representative of commonly employed alkali metal polyphosphates, useful in the compositions of this in vention, there may be mentioned the tetrasodium and tetrapotassium pyrophosphates, sodium and potassium tripolyphosphates, tetraphosphates, pentaphosphates, hexametaphosphates and mixtures of two or more thereof and the like.
The above defined reaction product of P 0 with a nonionic surface active agent may be prepared by the process described and claimed in the copending applications of Nunn and Hesse, Serial No. 852,188, filed November 12, 1959, and of Nunn, Serial No. 856,367, filed December 1, 1959, now respectively U.S. Patents 3,004,- 056 and 3,004,057. As described in the said Nunn and Hesse application, the reaction between the P 0 and the nonionic surface active agent is conducted under substantially anhydrous conditions and at a temperature below about C. In its preferred form, the reaction is carried out by adding the P 0 gradually, with vigorous agitation to the nonionic surface active agent in liquid form. The reaction is exothermic and cooling is in some cases necessary to keep the temperature below 110 C., since discolored and darkened products tend to be produced above this temperature. The reaction proceeds continu- 3,1 same ously during the addition of the P and is preferably followed by maintenance of the reaction mixture at ambient temperatures up to 110 C. for an additional period of time after completion of such addition to allow for complete solution of the P 0 and reaction with the nonionic surface active agent.
The exact chemical constitution of the products produced by the above described reaction is not definitely known in view of the recognized tendency of the P 0 to form complex products and polymers in such reactions with hydroxylic compounds. In general, the product will usually contain about to 45% of the secondary phosphate ester of the nonionic agent, to 80% of the primary phosphate ester, 0 to of unreacted nonionic agent, and small amounts of unidentified by-products.
By carrying out the reaction in the presence of a small amount of a phosphorus-containing compound selected from the group consisting of hypophosphorous acid, salts of hypophosphorous acid, phosphorous acid, and salts and esters of phosphorous acid, preferably sodium hypophosphite or hydrophosphorous acid, as described in said Nunn application, lighter colored or substantially colorless reaction products are obtained.
The nonionic surface active agents employed for reaction with P 0 are well known in the art and are disclosed along with suitable methods for their preparation in numerous patents and other publications. In general, they may be obtained by condensing a polyglycol ether containing the required number of alkenoxy groups or an alkylene oxide such as propylene oxide, butylene oxide, or preferably ethylene oxide, or mixtures thereof, with an organic compound containing at least 6 carbon atoms and a reactive hydrogen atom. As such compounds con-- taining a reactive hydrogen atom there may be mentioned alcohols, phenols, thiols, primary and secondary amines, and carboxylic and sulfonic acids and the r amides. These compounds may obviously contain more than one reactive hydrogen atom, i.e. more than one hydroxy, mercapto, amino, amido, carboxylic, sulfonic or sulfonamido group, each such group in the compound being reactive with the alkylene oxide in suitable proportions. The amount of alky lene oxide or equivalent condensed with the reactive hydrogen-containing compound, i.e. the length of the po-lyoxyalkylene chain, will depend primarily upon the particular compound with which it is condensed. As a convenient rule of thumb, amount of alkylene oxide or equivalent should be employed which will result in a condensation product containing about 20 to 95% by weight of combined alkylcne oxide. However, the optimum amount of alkylene oxide for attainment of the desired hydrophobic-hydrophilic balance may be readily determined in any panticular case by preliminary test and routine experimentation.
The reaction between the reactive-hydrogen-containing organic compound and the alkylene oxide in the production of the above described nonionic surface active agents is Well known in the art, being preferably carried out at elevated temperatures and pressures and catalyzed by quaternary hydroxides, amines, acids and/or coordinating type compounds although strong alkaline catalysts such as KOH or NaOH and the like are preferred because of fewer by-products formed and the more easily controlled reaction conditions. The reaction is substantially quantitative, although it will be understood that the product of this reaction between the alkylene oxide, preferably ethylene oxide, and the organic reactive hydrogen-containing compound will be a mixture of polyoxyalkylene derivatives of varying oxyalkylene chain length, the average of which substantially corresponds to the amount of alkylene oxide reactant. Such product will of course always contain an average of at least one hydroxy group (in a terminal C H OH group) per molecule.
In the production of the above described nonionic surface active agents, the following are illustrative examples of: types of organic compounds containing a reactive hydrogen atom:
(1) Aromatic monoand poly-hydroxy compounds such as phenols, naphthols, benzene and naphthalene diols, triols and tetrols and like. In this group, alkyl phenols are preferred containing 1 to 3 alkyl substituents of from 4 to 20 carbon atoms each. Some examples of such compounds are the normal and isomeric mono, di-, and tri-butyl, -nonyl, and octadecylphenols and cresols, and phenols and cresols substituted by a plurality of different such alkyl groups.
(2) Straight and branched chain, saturated and unsaturated aliphatic monohydric and polyhydric alcohols of natural or synthetic origin. Among this group are the alcohols derived from animal and vegetable sources such as lauryl alcohol, stearyl alcohol, and the like. Also included are the diol precursors of the Pluronic type nonionic surface active agents, generally prepared by polyoxyethylenation of a polymerized alkylene oxide of at least 3 carbon atoms, preferably propylene oxide, to produce the corresponding water insoluble polypropylene glycol having a molecular weight of up to about 3000, or of the reaction product of a plurality of moles of propylene oxide or substituted propylene oxide with alkylene diamines such as ethylene diamine and propylene diamine, polyalkylene polyamines, and alkane diols such as ethylone glycol, hexamethylene glycol, and the like. Tl ese agents of the Pluronic type may range in molecular weight from about 300 to 10,000. This group also includes the primary aliphatic alcohols containing a plurality of side chains. Such multi-branched chain alcohols may be produced by various methods, preferably by subjection of an olefin containing at least 7 carbon atoms and at least 2 side chains, such as tripropylene, tetrapropylene, pentapropylene, diisobutylenc, triisobutyiene, and the like to the Oxo process, involving the catalytic reaction of the olefin with carbon monoxide and hydrogen to form an aldehyde followed by catalytic reduction of the aldehyde to the corresponding primary alcohol. Other alcohols in this group are the essentially straight chain alcohols produced from Fischer-Tropsch olefins by the Oxo process or those produced by oxidation of Ziegler type polymer intermediates. Such intermediates, or mixtures thereof, made by polymerizing ethylene with a metal (cg. aluminum) alkyl, have an even number of carbon atoms averaging 10 to 24 per molecule in the chain.
(3) Higher fatty acids of amimal and vegetable origin and mixtures containing the same, such as lauric acid, oleic acid, stearic acid, the animal and vegetable fats and oils containing same, or the acids derived by oxidation of suitable etroleum fractions.
(4) Aliphatic and aromatic monoand polyiercapto compounds including cetyl mercaptan, dodecyi mercaptan, alkyl naphthylamine, alkyl thiophenol, thionaphthol, and the like.
(5) Aliphatic and aromatic monoand poly-amines, including laurylamine, stearylamine, alkyl benzylamine, alkyl naphthylamine, dodecylene diamine, tetrapropylene pentamine, and the like.
(6) Carboxylic acid amides such as lauric acid amide, stearic acid amide and the like.
(7) Sulfonamides and such as dodecyl sulfonamide, dodecylbenzene sulfonamide, and the like.
These and other types of organic compounds containing reactive hydrogen atoms suitable for reaction with alkylene oxides are disclosed for example in United States Patents 1,970,578, 2,002,613, 2,085,706, 2,174,761, 2,205,- 021, 2,213,477, 2,266,141, 2,593,112, 2,674,619, 2,677,- 760, 2,766,212 and others.

In general, the nonionic surface active agents preferred herein for the production of the desired reaction products with P are the polyoxyethylenated derivatives of alkyl phenols and aliphatic alcohols, containing at least carbon atoms, such as the polyoxyethylene ethers of coco alcohols containing an average of 12 carbon atoms, nonylphenol, dodecylphenol, dinoylphenol, and Oxo tridecyl alcohol as derived from tetrapropylene or triisobutylene.
It has also been determined that reaction products in the range of about 2 to 3.5 and preferably 2 to less than 3 hydroxy groups in the nonionic surface active agent per mole of P 0 have increased solubility and a lower proportion of free unreacted (non-phosphated) nonionic. Since increasing proportions of nonionic in dry alkali formulations yield increased discoloration, the use of such reaction products is preferred when formulating alkaline compositions in accordance with this invention, particularly when a dry formulation or a highly soluble formulation is desired. However, it will be understood that reaction products in the broader range of 2 to 4.5 hydroxy groups in the nonionic per mole of P 0 may be employed, that such reaction products may be used in the form of the free acid or soluble salts thereof with alkali metals and the like, and that the compositions of this invention may be provided in any desired form such as liquid concentrates, powders, shaped compositions, pastes and the like.
For most purposes, the objects of this invention may be attained with mixtures, in dry or particulate form or in aqueous solution, of about 0.002 to 25 parts of the above defined phosphate ester reaction products for each part by Weight of the alkaline reacting substance.
The compositions of this invention may also include 0 to about 25% by weight of one or more of the other usual constituents of highly alkaline cleaning and/ or surface active compositions, as for, example one or more neutral inorganic salts such as sodium and potassium chloride and sulfate and the like; soil suspending agents, these being generally water soluble polymeric materials such as cellulose glycollic acid, cellulose ethane sulfonic acid, hydroxyethyl methyl cellulose, starch, hydroxyethyl starch, starch glycollic acid, lichenin, xylan, polymeric carboxylic acids such as copolymers of maleic anhydride with styrene, vinyl methyl ether and vinyl ethyl ether, polyvinylpyrrolidone and the like; perfumes; deodorants; disinfectants; corrosion inhibitors; sequestrants such as ethylenediamine tetracetic acid, sodium gluconate and polyhydric sugar acids and the like; foam stabilizers such as dialkanolamides of fatty acids and the like; hydrotropes or solubilizers such as sodium xylene and toluene sul- 6 fonate and the like; other anionic or nonionic surfactants such as higher alkyl (e.g. lauryl) sulfates, alkylaryl sulfonates (e.g. dodecyclbenzene sulfonate), sodium taurides, fatty acid soaps, nonionics described above, etc.
The highly alkaline surface active compositions are useful and highly effective as electrolytic cleaners, metal processing cleaners, alkaline descaling and derusting agents, steam cleaners, metal soak cleaners, aluminum cleaners, aluminum milling agents, alkaline dairy cleaners, :bottle :Washing agents, paint strippers, wax strippers, heavy duty industrial cleaners and degreasers (for fabrics, industrial clothing, curtains, belting, floors, castings, engines, railroad cars, trucks, buses), paper digestor additives (for wetting, peptizing and dispersing action), paper de-inking agents (for dispersing and emulsifying action), and the like.
The following examples are only illustrative of the present invention and are not to be regarded as limitative. All parts and proportions referred to herein and in the appended claims are by Weight unless otherwise indi cated. All these exemplified compositions have, in 0.3% aqueous solution, a pH of more than 12. i
The constitution of representative phosphate ester surfactants is disclosed in Table A. All are prepared by reaction between P 0 and the designated nonionic surfactant precursor in the stated molar proportions and in the presence of sodium hypophosphite following the procedure described in the examples in said Nunn application Serial No. 856,367. 130. means ethylene oxide, its proportion in the defined nonionic surfactant being expressed in moles per mole of reactive hydrogen containing compound and/or in weight percent in the nonionic surfactant.

In the table, SMS means sodium metasilicalte, so means soluble giving a clear solution at temperatures up to boiling, and sepf means that a separation of the phosphate ester from solution has occurred, usually in the form of a lrazy tor cloudy suspension. In common with the nonionic surfactant precursors, the solubility of the corresponding phosphate ester surfactants generally decreases with increasing temperatures. Where a number appears in the table, it refers to the maximum temperature in degrees centigrade at which the phosphate ester surfactant is completely soluble and the solution clear. The examples in the table show the unusual solubility and compatibility of the indicated phosphate esters in aqueous solutions [of sodium hydroxide and sodium metasilicate. The table also shows the effect of variation in oxyethylene content \of the nonionic surfactant precursor upon the solubility in alkalies of the corresponding phosphate ester and the effect. of decreasing ratios of nonionic to P 0 In general, it is apparent that, other things being equal, highest solubilities are obtained 7 with proportions of nonionic precursor to P below in general, other things being equal, optimum color stav3.5:1 and ranging from about 2.5:1 to 2.8:1 for the cornbility is obtained with proportions of nonionic precursor positions tested.
