| 摘 要： | 利用共沉淀法由Fe(NO3)3、Al(NO3)3、Zn(Ac)2和H2SO4制备了SO42-/Fe2O3/Al2O3/ZnO催化剂,并用于催化合成苯甲醛丙二醇缩醛,研究了醛醇摩尔比、催化剂用量、反应时间等因素对产品收率的影响。结果表明,在n(苯甲醛)∶n(丙二醇)=1∶1.2,催化剂用量为反应物总质量的1%,反应时间50 min的最佳条件下,苯甲醛丙二醇缩醛的收率可达97.6%。

| Abstract: | The SO42-/Fe2O3/Al2O3/ZnO solid acid catalyst was prepared from Fe(NO3)3 · 9H2O and Al(NO3)3 · 9H2O and Zn(Ac)2 by a co-precipitation method.And used as catalysts for the synthesis of benzaldehyde 1,2-propanediol acetal.Influence of aldol molar ratio,catalyst amount,reaction time on product yield.The results showed that n(benzaldehyde)∶ n(propanediol) is 1∶ 1.2,the amount of catalyst 1% of the total mass of reactants,under the optimum conditions of the reaction time of 50 min,the yield of benzaldehyde 1,2-propanediol acetal was up to 97.6%. |
