Abstract

A process for the preparation of 3 ', 4'-dichloropropionanilide, characterized by mixing 3,4-dichloroaniline with propionic acid, the propionic acid being in a molar ratio in excess of 10 to 125% above that required to form the propionate of , 4-dichloroaniline, heat the mixture to reflux temperature, remove the azeotrope propionic acid-water as it is formed while returning essentially pure propionic acid condensate to the reaction vessel, continue the extraction of the azeotrope until the approximately theoretical amount of water, and distilling off the remaining propionic acid, leaving 3 ', 4'-dichloropropionanilide as the reaction residue.
