Electrolytic method to make alkali alcoholates using ceramic ion conducting solid membranes
Abstract:
Disclosed are processes of making solutions of alkali alkoxides in their corresponding alcohols using an electrolytic process. In one embodiment, sodium methoxide in methanol is made from methanol and aqueous sodium hydroxide solution, where the aqueous sodium hydroxide solution is present in the anolyte compartment and a solution of sodium methoxide in methanol is present in the catholyte compartment, the two compartments are separated by a ceramic membrane that selectively transports sodium ions under the influence of an electric potential, and wherein the composition of the solution of sodium methoxide in methanol in the catholyte compartment of the electrolytic cell comprises between at least about 2% by weight sodium methoxide and at most about 20% by weight sodium methoxide.
