以四水硫酸锆为催化剂合成了环己酮乙二醇缩酮,并获得了较佳合成条件:环己酮为0.2mol,n(环己酮)∶n(乙二醇)=1∶1.5(摩尔比),催化剂用量为1.00g,25mL苯作分水剂,反应时间为2.5h,产率为85.6%.实验结果表明该催化剂具有较高的催化活性,产品纯度可达97.2%(GC分析). Cyclohexanone ethylene ketal was synthesized by using zirconium sulfate tetrahydrate as catalyst. The optimum synthesis conditions were as follows: cyclohexanone 0.2mol, n (cyclohexanone): n (ethylene glycol) = 1: 1.5 (Molar ratio), the amount of catalyst is 1.00g, 25mL benzene as the water-splitting agent, the reaction time is 2.5h, the yield is 85.6% .The experimental results show that the catalyst has high catalytic activity, the purity of the product can reach 97.2% analysis).
