Abstract
Disclosed is an improved process for reacting a halogenated ester with an alkali metal alkoxide to form an alkoxy ester and a salt. A solvent is added to the halogenated ester prior to the addition of the alkali metal alkoxide. This results in a substantial increase in the particle size of the salt which greatly facilitates its separation from the solution of the alkoxy ester product.
