以苯磺酸酮为催化剂,环己酮与1,2-丙二醇合成了环己酮1,2-丙二醇缩酮。研究了环己酮与1,2-丙二醇量比、催化剂用量、反应时间诸因素对收率的影响。结果表明,苯磺酸酮是合成环己酮1,2-丙二醇的良好催化剂。在环己酮与1,2-丙二醇的投料摩尔比为1∶1.5、催化剂的用量占反应物料总质量的2%、带水剂环己烷的用为10mL、反应时间为40min条件下,环己酮1,2-丙二醇缩酮的收率可达75.4%。

Cyclohexanone 1,2-propanediol ketal was synthesized from cyclohexanone and 1,2- propanediol in the presence of copper benzene sulfonate . The factors influencing the synthesis were discussed and the best conditions were found out. The optimum conditions are： molar ratio of cyclohexanone to 1,2-propanediol is 1：1.5, the quantity of catalyst is equal to 2% of feed stocks, and the reaction time is 40 min. Copper benzene sulfonate is an excellent catalyst for synthesizing cyclohexanone 1,2-propanediol ketal and its yield can reach 75.4%.
