摘　　要：以交联的聚芳醚酮酮和发烟硫酸(含ＳＯ320%)合成了磺化聚芳醚酮酮树脂,并用于苯乙酸和β-苯乙醇的催化酯化.最佳条件:β-苯乙醇12.22ｇ,催化剂用量为1.0ｇ,反应温度为145～155℃,反应时间为4.5ｈ,酯化率达90.5%.催化剂易回收且可重复使用.The sulfonated polyaryletherketoneketone(S-PKKK) was synthesized from cross-linking polyaryletherketoneketone with 20% fuming sulphuric acid, and then it was use as catalyst in esterification of phenylacetic acid and β-phenethyl alcohol. The optimum reaction conditions were obtained as follows phenylacetic acid 17.70 g, β-phenethyl alcohol 12.22 g, S-PEKK 1.0 g, reaction temperature was 145～155 ℃, reaction time was 4.5 h,yield of the easter was 90.3%. The catalyst could be reclaimed easily and used repeatedly.
