摘　　要：以Cu_3(BTC)_2负载磷钨酸H_3PW_(12)O_(40)/Cu_3(BTC)_2催化剂催化,环己酮和乙二醇为原料合成环己酮乙二醇缩酮.探讨H_3PW_(12)O_(40)/Cu_3(BTC)_2对环己酮乙二醇缩酮的催化活性,较系统地研究了酮醇物质的量比、催化剂用量、带水剂用量、反应时间等因素对产物收率的影响.实验表明:H_3PW_(12)O_(40)/Cu_3(BTC)_2是合成环己酮乙二醇缩酮的良好催化剂,在n(环己酮)∶n(乙二醇)=1∶1.4,催化剂用量占反应物料总质量0.6%,带水剂环己烷的用量为8 m L,反应时间45 min的最佳条件下,环己酮乙二醇缩酮的收率可达75.9%.A new environmental friendly catalyst, H3PW12 O40/Cu3 （BTC）2was prepared with the impregnation method, and characterized by FF - IR and XRD. Cyclohexanone ethylene ketal was synthesized from cyclohexanone and glycol using HaPW12O40/Cu3 （BTC）2 as the catalyst. The influence factors on the yield of cyclohexanone ethylene ketal were also discussed. The optimum conditions were indentified ： molar ratio of cyclohexanone and glycol is 1： 1.4, mass fraction of catalyst to reactants is 0.6% , cyclohexane dosage is 6 mL and reaction time is 45 minutes. The yield of cyclohexanone ethylene ketal can reach 75.9% under the optimum conditions.
