Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur elektrochemischen Herstellung von Alkalialkoholaten sowie eine für diesen Zweck einzusetzende Elektrolysezelle, bei der anodenseits wäßrige Salzlösungen eingesetzt werden.The present invention relates to a method for electrochemical production of alkali alcoholates and an electrolytic cell to be used for this purpose, in the case of aqueous salt solutions on the anode side be used.

Diese Maßnahme wird durch die Trennung von Anoden- und Kathodenraum durch einen anolyt- bzw. katholytstabilen Festelektrolyten, insbesondere β-Aluminiumoxid, erreicht.This measure is achieved through the separation of anode and Cathode compartment through an anolyte or catholyte stable Solid electrolytes, especially β-alumina, reached.
