PRODUCTION OF AROMATIC POLYHYDRIC ALCOHOL

摘要

PURPOSE:To produce an aromatic polyhydric alcohol in a high yield by catalytically hydrocracking an aromatic polybasic carboxylic acid ester. CONSTITUTION:When an aromatic polybasic carboxylic acid ester is catalytically hydrocracked to produce an aromatic polyhydric alcohol, the ester of an aromatic polybasic carboxylic acid with a monohydric alcohol derived from a >=6C alkane is employed as the raw material, and a catalyst containing copper, chromium, barium and/or manganese is also employed as the catalyst in the presence of a basic substance. The aromatic polyhydric alcohol is produced in high conversion and in high selectivity.
