METHOD FOR PRODUCING CARBOXYLIC ACID ESTER, ESTERIFICATION AGENT AND RING-OPENING ADDITION CATALYST
-
Paragraph 0218, (2017/11/04)
PROBLEM TO BE SOLVED: To provide a method for producing a carboxylic acid ester using a catalyst compound which is easy to handle and has high activity and to provide an esterification agent and a ring-opening addition catalyst suitably used for the production method. SOLUTION: An imidazole compound having a specific structure is allowed to exist during a reaction when a carboxylic acid ester is produced by reacting (A) at least one electrophilic body selected from the group consisting of at least one hydroxy group-donating compound selected from the group consisting of a phenol compound and alcohol and an epoxy group-donating compound composed of an epoxy compound and (B) at least one nucleophilic body selected from the group consisting of carboxylic acid, a carboxylic acid halide, a carboxylic acid ester and a carboxylic acid anhydride.
