以硫酸铈铵为催化剂,以环己酮和1,2-丙二醇为原料合成了环己酮-1,2-丙二醇缩酮,通过正交实验优选反应条件,研究了反应物料配比、催化剂用量、反应时间等因素对反应的影响。结果表明,在n(环己酮)∶n(1,2-丙二醇)=1∶1.5,催化剂用量为反应物料总质量的1.4%,带水剂环己烷12mL,反应时间60min的优化条件下,环己酮-1,2-丙二醇缩酮的收率可达65.9%。
Cyclohexanone-1,2-propanediol ketal was synthesized from cyclohexanone and 1,2-propanediol using ceric ammonium sulfate as catalyst. The reaction conditions were optimized by orthogonal experiments. The effects of the amount of catalyst, , Reaction time and other factors on the reaction. The results showed that under the optimal conditions of n (cyclohexanone): n (1,2-propanediol) = 1: 1.5, the amount of catalyst was 1.4% of the total mass of the reaction mass, 12 mL of cyclohexane and the reaction time was 60min , Cyclohexanone-1,2-propanediol ketal yield of up to 65.9%.
