【Abstract】 The sulfonated poly aryl ether ketone ketone was synthesised by reaction of cross_linking poly aryl ether ketone ketone with 20% fuming sulpburic acid as sulfonating agent and used to catalyze the synthesis of n_butyl acetate. The optimal conditions of preparation were obtained: the molar ratio of acid to alcohol was 1/1.6, the amount of catalyst was 4.35%,the amount of acetic acid.reaction temperature was 115～120 ℃,reaction time was 4 h. Yield of the easter was 87.5%. The catalyst could be reclaimed easily and used repeatedly.更多还原
