Abstract
Disclosed are processes of making solutions of metal alcoholates in their corresponding alcohols using an electrolytic process. In a preferred embodiment, sodium methylate in methanol is made from methanol and sodium hydroxide solution. The sodium hydroxide solution is placed in the anolyte compartment and the methanol is placed in the catholyte compartment, and the two compartments are separated by a ceramic membrane that selectively transports sodium under the influence of current. In preferred embodiments, the process is cost-effective and not environmentally harmful.
