摘　　要：以硫酸铜为催化剂,通过丁酮与1,2-丙二醇反应合成了丁酮1,2-丙二醇缩酮。较系统地研究了酮醇量比、催化剂用量、带水剂用量及反应时间等条件对收率的影响。结果表明:在n(丁酮)∶n(1,2-丙二醇)=1∶1.5,催化剂用量为反应物料总质量的5.4%,环己烷作带水剂20mL,反应时间3.0h的优化条件下,丁酮1,2-丙二醇缩酮的收率可达60.8%.Butanone 1,2- propanediol ketal was synthesized from butanone and 1, 2 -propanediol in the presence of copper sulfate. The factors influencing the synthesis were investigated. The optimum conditions were found. The optimum conditions were as follows ： molar ratio of butanone to 1,2 - propanediol is 1 ： 1.5, the mass ratio of the catalyst used to the reactants is 5. 4% , and the reaction time is 3h. Copper sulfate is an excellent catalyst for synthesizing butanone 1,2 - p ropanediol ketal and the product yield can reach over 60.8%.
