| 摘 要： | 用绿色催化剂磷钨酸镍催化合成了苯甲醛乙二醇缩醛,研究了催化剂用量、醛醇物质的量比、反应时间、带水剂用量、催化剂重复使用性能等因素对产率的影响。实验结果表明反应的最佳条件为:在苯甲醛0.2 mol、n(醛)∶n(乙二醇)=1.0∶1.5、m(NiPW)=0.8 g、反应温度86~90℃、反应时间为2.0 h、V(环己烷)=24 mL的条件下,产率可达到81.6%。

| Abstract: | Benzaldehyde glycol acetal was synthesized in the presence of nickel phosphotungstate. The various factors influencing the synthesis were investigated and the optimum conditions were found as follows：based on benzylaldehyde 0.2 mol,n（benzylaldehyde） ： n（ethylene glycol）= 1 ： 1.5,re（nickel phosphot ungstate） = 0. 8 g,V（cyclohexane） = 24 mL, reaction time 2. 0 h, at 86 - 90 ℃, the yield of acetal could reach 81.6%. |
