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.
Diese Maßnahme wird durch die Trennung von Anoden- und Kathodenraum durch einen anolyt- bzw. katholytstabilen Festelektrolyten, insbesondere β-Aluminiumoxid, erreicht.
