PURPOSE: To obtain the subject compound in high selectivity by carrying out dehydrohalogenative condensation reaction of an aromatic compound and a trilhalogenomethylbenzene compound in the presence of an acid catalyst using a crystalline aluminosilicate as a delhydrohalogenative condensation reaction catalyst and hydrolyzing the condensation product.

CONSTITUTION: The objective benzophenone compound (e.g., 4,4'- dichlorobennzo-phenone) can be produced in high selectivity by carrying out dehydrolhalogenative condensation reaction of an aromatic compound and a trihalogenomethylbenzene compound in the presence of an acid catalyst using a crystalline aluminosilicate having an effective pore diameter of ≥6 and a silica/alumina mol ar ratio of 4-200 (e.g., Y-zeolite, mordenite or β-zeolite) as a dehydrohalogenative condensation reaction catalyst and hydrolyzing the obtained benzophenone dihalogenide. The process has various industrial merits such as easy separation of the product and the catalyst, reduced cost of waste acid treatment, reusability of catalyst, etc.
