Butanone glycol ketal was synthesized from Butanone and glycol in the presence of H3 PW12 O40/SiO2 as catalyst.The optimal reaction conditions were screened by orthogonal test method.The yield of Butanone Glycol Ketal can reach 83.6%under the optimum reaction conditions that Butanone is 0.2mol, molar ratio of Butanone to glycol is 1.0∶1.4, the quantity of catalyst is 1.0%, the cyclohexane as carrying-water reagent is 8mL and the reaction time is 75min.%以二氧化硅负载磷钨酸（ H3 PW12 O40/SiO2）为催化剂，用丁酮和乙二醇为原料催化合成了丁酮乙二醇缩酮．正交实验法探讨得出的适宜反应条件为：固定丁酮用量0．2 mol，在n（丁酮）∶n（乙二醇）＝1．0∶1．4，催化剂用量占反应物量总质量的1．0％，环己烷为带水剂8 mL，反应时间75 min的最佳条件下，丁酮乙二醇缩酮的收率可达83．6％．
