Biphenol AP is synthesized using phosphato—tungstic heteropoly acid as major catalyst. The main factors of influencing the synthesis reaction are analyzed, and the best technological parameters of the synthesis reaction are obtained by orthogonal experiments: the molar ratio of phenol to acetophenone is 5:1, reaction temperature is 120 ℃, the mass fractions of major catalyst is 6%, the dosage of auxiliary catalyst is 0.15 mL, reaction time is 4 h. The yield rate of bisphenol AP is 54.5%.
