ABSTRACT:
The concentration of alkali metal hydroxide contaminants in solutions of alkali metal alkoxides in alcohols is reduced to below about 0.1 percent by adding an alkyl alkanoate ester. For example, a solution of sodium methoxide in methanol containing about 0.04 percent sodium hydroxide was obtained by adding a small amount of methyl acetate. The alkali metal alkanoate salt formed as a by-product does not deleteriously affect most uses of such solutions.
