Abstract

A process for electrochemical preparation of an alkali metal alkoxide solution is performed in an electrolysis cell having three chambers. The middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to cations, for example NaSICON, and from the anode chamber by a diffusion barrier, for example a membrane selective for cations or anions.
