| titleOfInvention | Method for producing polyhydroxybenzophenones |
| abstract | PROBLEM TO BE SOLVED: To provide high-yield, high-purity polyhydroxybenzophenones without using complicated production operations and hardly generating harmful and difficult-to-treat wastes, Enables significant cost reduction. SOLUTION: The benzoic acid represented by the following general formula (1) and a phenol represented by the following general formula (2) are continuously converted into water produced by the reaction in the presence of an acid catalyst. In the method for producing polyhydroxybenzophenones represented by the following general formula (3) by reacting while removing, the product is continuously crystallized and taken out of the reaction system.
