摘　　要：以氯铝酸N,N二甲基苯胺盐酸盐离子液体为催化剂,催化苯酚和丙酮缩合反应合成双酚A.通过与无机催化剂三氯化铝对比,得出最佳反应条件：物质的量之比（苯酚∶丙酮∶离子液体=8∶1∶1）,反应溶剂甲苯,反应温度45℃等,产物熔点155.8～158.2℃,产率最高为88.7%.Taking aluminum chloride acid N,N-dimethylaniline hydrochloride ionic liquid as catalyst,bisphe-nol A was synthesized by condensation of phenol and acetone.Compared with the inorganic catalyst aluminum chlo-ride,the optimal reaction were as follows:the molar ratio of phenol∶acetone∶ionic liquids was 8∶1 ∶1 ;toluene was regarded as the reaction solvent ;the reaction temperature was maintained at about 45 ℃,the determined melting point range of product was 1 55.8 ~1 58.2 ℃.The yield could reach up to 88.7%.
