摘　　要：合成了聚苯胺-碘(PAn-I2)催化剂,并对其结构进行了表征。并通过环己酮与1,2-丙二醇合成环己酮1,2-丙二醇缩酮,探讨了PAn-I2对缩酮反应的催化活性。实验结果表明,PAn-I2是缩酮反应的良好催化剂,在环己酮100 mmol,n(环己酮)∶n(1,2-丙二醇)=1∶1.5,催化剂用量为反应物总质量的3%,环己烷12 mL,反应时间2 h的优化条件下,环己酮1,2-丙二醇缩酮的收率可达92.1%。A new environmentally-friendly catalyst, polyaniline doped with iodine（ PAn-I2 ）, was prepared. Cyclohexanone 1,2-propylene ketal was synthesized from cyclohexanone and 1,2-propylene alcohol in the presence of PAn-I2. Factors influencing the product yield were discussed and the optimal reaction conditions were found. Experimental results showed that PAn-I2 is an excellent catalyst. With cyclohexanone 100 mmol, n （cyclohexanone） ： n （1,2-propylene） = 1 ： 1.5, w （ polyaniline doped with iodine） = 3%, cyclohexane 12 mL and refluxing for 2.0 h, the yield of cyclohexanone 1, 2-propylene ketal can reach 92. 1%.
