【Abstract】 Taking aluminum chloride acid N,N-dimethylaniline hydrochloride ionic liquid as catalyst,bisphenol A was synthesized by condensation of phenol and acetone. Compared with the inorganic catalyst aluminum chloride,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 155. 8 ~ 158. 2 ℃. The yield could reach up to 88. 7%.更多还原
