DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 45 The prodn. of (un)substituted arylcarboxylic acid chlorides (e.g., 2,4,6-trimethylbenzoyl chloride) is achieved via the Friedel-Crafts-catalyzed methylation of (un)substituted aroms. (e.g., 1,3,5-trimethylbenzene) with tetrachloromethane and subsequent acid hydrolysis of the (un)substituted benzotrichloride using a protic acid (e.g., chloroacetic acid) and water. .
