<p>A process for producing a halomethyl ester of an aliphatic carboxylic acid by the reaction of a metallic salt of the acid with a dihalmethane in the presence of a phase transfer catalyst. The above reaction makes it possible to produce the halomethyl ester in good yields without forming halomethyl ether as by-product. This process is suitable for the industrial production of a halomethyl ester of an aliphatic carboxylic acid, because a bis-(aliphatic carbonyloxy)methane formed as a by-product is quantitatively hydrolyzed into an aliphatic carboxylic acid which can be recovered for reuse.</p> |
