Procedure

To a 70 ml pressure-resistant reactor, 0.35 g of Catalyst 7 prepared in (2), 6.63 g of phenol, and 0.37 g of acetone were charged, and the reactor was pressurized with nitrogen gas under 0.5 MPa of a gauge pressure, and then the reaction was conducted with heating and stirring at 75° C. for 2 hours. Thereafter, the resultant was cooled to room temperature. After the pressure discharge, the reaction solution was taken out, and analytically quantified by a liquid chromatography method. As a result, the conversion of acetone was 94.8% and the selectivity of pp′-bisphenol A was 94.1%.
