摘　　要：报道了以磷钨钼杂多酸掺杂聚苯胺为催化剂,通过丁醛和乙二醇反应合成了丁醛乙二醇缩醛。系统考察了醛醇物质的量比、催化剂用量以及反应时间诸因素对产品收率的影响。确定适宜的工艺条件为n(丁醛)∶n(乙二醇)=1∶1.5,催化剂的质量为反应物料总质量的0.8%,反应时间1.0 h。在此反应条件下,丁醛乙二醇缩醛的收率可达71.1%。Catalytic activities of H_3PW_6Mo_6O_(40) /PAn in synthesizing butyraldehyde glycol acetal were reported.It has been demonstrated that H_3PW_6Mo_6O_(40) /PAn is an excellent catalyst.Various factors concerned in the reaction have been investigated.The optimum conditions have been found,that is,the molar ratio of butyraldehyde to glycol is 1/1.5,the mass ratio of the catalyst used to the reactants is 0.8%,and the reaction time is 1.0 h.Under these conditions,the yield of butyraldehyde glycol acetal is 71.1%.
