Description
NITED STATES T T FFICEQ THEODOR KEMPF, OF BERLIN, GERMANY, ASSIGNOR TO THE CHEMISCHE FABRIK AUF AOTIEN, OF SAME PLACE.
MANUFACTURE OF IODOFORM, BROMOFORM, AND CHLOROFORM.
SPECIFICATION forming part of Letters Patent No. 322,940, dated July 28, 1885.
Application filed June 5,1884. (No specimens.) Patented in Germany March 7, 1884, No. 29,771; in England May 23, 1884,170. 8,148; in France May 23, 1884, No. 162,306; in Belgium May 23,1884, No. 65,227; in Luxemburg May 24, 1884, No. 405, and in Austria-Hungary September 23, 1884, No, 19,725 and No. 42,228.
To all whom it may concern.-
Be it known that I, THEODOR KEMPF, a subject of the King of Prussia, residing at Berlin, Prussia, German Empire, have invented certain new and useful Improvements in the Process of Manufacturing Iodoform, Bromoform, and Ohloroform, (for which Letters Patent have been issued in Great Britain, No. 8,148, dated May 23, 1884, to myself; and to The Ghemische Fabrik auf Actien, Vorm. E. Schering, in the following countries; France, No. 162,306, dated May 23, 1884; Belgium, No. 65,227, dated May 23, 1884; Germany, No. 29,771, dated March 7, 1884; Luxemburg, N0. 405, dated May 24, 1884; Austria-Hungary, No. 19,725 and No. 42,228, dated September 23, 1884;) and I do hereby declare the fol lowing to be afull, clear, and exact description of the invention.
This invention relates to the production of iodoform, bromoform, and chloroform by electrolysis from the corresponding halogen combinations of the alkalies and alkaline earths in the presence of alcohol, aldehyde, or acetone and heat. If, for example, it is desired to obtain iodoform, I dissolve fifty kilograms of iodide of potassium in about three hundred kilograms ofwater, to which I add about thirty kilograms of alcohol of ninety-six per cent. This solution is then subjected to electrolysis in a suitable Vessel under a continuous introduction of carbonic acid and the application of heat. The iodoform obtained separates from the solution in a crystalline powder.
To obtain iodoform in large crystals, the iodide of potassium is dissolved in about twenty per cent. of alcohol, and subjected to the electrolysis described.
To produce bromoform or chloroform, the corresponding halogen combinations are subjected to electrolysis in the same manner as above described, except that no carbonicaoid is used.
In carrying out the above processes the carbonic dioxide employed in the production of 5 iodoform is introduced directly into the alcoholic solution of iodide of potassium, and simultaneously with the electric current.
I have found that an electric current of the strength of about sixty amperes will be sufficient to effect the decomposition of the solution mentioned.
The duration of the action of the electric current upon the solutions will naturally de pend upon their volume, said solutions being subjected to the action of the electric current until complete decomposition has been effected.
In the production of iodoform an alcoholic solution of iodide of potassium of any desired degree of concentration may be employed, the iodoform being separated from the alkali carbonate in the lye by simple filtration.
The chloroform or bromoform developed during the decomposition of the respective chloride or bromide solutions i. 6., their respective halogen combinationsis continuously distilled from the decomposing cell as it is developed.
Having now described my invention, what I claim is- The herein-described process of obtaining iodoform, bromoform, and chloroform, which consists in subjecting the corresponding halogen combinations of the alkalies or alkaline earths to electrolysis in the presence of alcohol, aldehyde, or acetone and heat, and with or without the addition of carbonic acid.
In testimony whereof I affix my signature in presence of two witnesses.
