ABSTRACT:
The yield of metal alkoxides formed by refluxing an alcohol-containing liquid, also containing catalyst, from a reactor vessel into a reflux column containing reactive metal is provided. The yield of the desired alkoxide is increased by withdrawing a portion of the alcohol reactant and catalyst from the reactor and introducing them into the column above the position occupied by at least a portion of the metal. The thus introduced catalyst-containing alcohol reactant makes contact with the metal and thereby increases the yield of metal alkoxide as it is allowed to flow back into the reactor vessel.
