Abstract
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%.
