Abstract

PURPOSE: A phenol and a carboxylate are subjected to carbonylation with CO to give a carboxylic acid and a carboxylic acid aryl ester, to which an alcohol is added to undergo transesterification and to prepare the phenol and the carboxylate, which are used raw materials.
CONSTITUTION: A phenol (e.g., phenol, cresol) and a carboxylate [e.g., RCOOR' (R and R' are aromatic or aliphatic)] are subjected to carbonylation with CO to give a carboxylic acid and a carboxylic acid aryl ester. The carboxylic acid is separated from a reaction product, and an alcohol is added to the remaining carboxylic acid aryl ester. The resulting compounds undergo transesterification in the presence of a catalyst, e.g., phosphoric acid, trimethylamine, to give the phenol and the carboxylate, which are used as raw materials in carboxylation. Water is hardly formed in the transesterification so that a reaction system is maintained in a noncorrosive atmosphere and this method is very advantageous with respect to material.
