Abstract

Die Erfindung beschreibt ein Verfahren zur Elektrolyse einer wässrigen Lösung von Alkalimetallchlorid, insbesondere Natriumchlorid, nach dem Membranverfahren mit einer wässrigen Lösung von Alkalimetallhydroxid, insbesondere Natriumhydroxid, als Katholyt, wobei die Temperatur der Alkalimetallchloridlösung in dem Anodenhalbelement und/oder der Volumenstrom der Alkalimetallchloridlösung in dem Anodenhalbelement so eingestellt werden, dass die Differenz zwischen der Temperatur der Alkalimetallhydroxidlösung am Eintritt in das Kathodenhalbelement und der Temperatur der Alkalimetallhydroxidlösung am Austritt aus dem Kathodenhalbelement nicht größer als 15 °C beträgt.
