ABSTRACT:
A catalyst for producing an aryl ester of a carbonic or carboxylic acid is disclosed, which includes a microporous material containing a metal element belonging to group IV. This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.
