PRODUCTION OF 2-PHENOXYBENZOIC ACID

摘要

PURPOSE:To obtain a method for industrially and advantageously producing 2-phenoxybenzoic acid using 2-chlorobenzoic acid as a starting raw material. CONSTITUTION:The objective method for producing 2-phenoxybenzoic acid of formula III is to make 2-chlorobenzoic acid of formula I react with a phenolic derivative of formula II [R is H or lower alkyl; (n) is 1-5] in the presence of a copper salt and an alkylamine and convert the 2-chlorobenzoic acid into the 2-phenoxybenzoic acid.
