Abstract

A process can be used for preparing sodium and potassium alkoxides. The process is characterized by two simultaneously implemented but spatially separated reactions of an alcohol ROH with NaOH, and ROH with KOH, to give sodium alkoxide and potassium alkoxide, respectively. The vapours formed in this case contain the alcohol used and water. The vapours are combined, and the resulting mixed vapour is fed to a common distillation with recovery of the alcohol.
