The reaction factors for the formation of bisphenol A and B, or the raw materials for polycarbonate resin, have been investigated. Bisphenol A was prepared with Hasen No, 70 and 91% yield of the theory by reaction of 3 moles of phenol, 1 mole of acetone, 0-0.02 mole of mercaptoacetic acid, and 0.36 mole of hydrogen chloride gas for 8 hours, and washing with hot water, distillation in vacuum and recrystallization. Similarly, bisphenol B with Hasen No. 100 was prepared with 76% yield of the theory.
