摘　　要：以活性炭为载体,通过浸渍法制备了H9P2W15V3/C催化剂,对催化剂进行FT-IR表征。以催化1,4-丁二醇脱水制备四氢呋喃为探针反应,考察催化剂的酸催化性能。通过正交实验得出了最佳条件反应:w(催化剂)=3.93%(相对1,4丁二醇质量),反应温度为185～190℃,反应时间为40 min,四氢呋喃平均收率达93.30%,催化剂重复使用3次,产率仍可达90.94%。本工艺具有绿色、安全、操作简单、收率高等优点。Tungstovanadophosphoric heteropoly acid with tri-vanadium-substituted Dawson structure supported by activated carbon was prepared by impregnation method and characterized by IR. Its catalytic performance was studied in the catalytic synthesis of tetrahydrofuran from 1,4-butanediol. The optimal reaction condition was obtained by orthogonal experiments as mass ratio of 1,4-butanediol to catalyst 100 ： 3.93, reaction temperature 185--190 ~C and reaction time 40 rain, under which, the yield of tetrahydrofuran reached 93.30%. The catalyst could be reused for 3 times and the yield was still above 90.94%. This approach provides a green, safe, operation simple and highly active dehydration process to produce THF.
