Catalytic synthesis of butanone 1,2-propanediol ketal with cerium sulfate

Butanone 1,2-propanediol ketal was synthesized from butanone and 1,2-propanediol using cerium sulfate as catalyst.The factors influencing the synthesis were investigated.The optimum conditions were as follows: n(butanone):n(l,2-propanediol) is 1:1.5,w(catalyst) is 1.6%,and the reaction time is 75min.Cerium sulfate is an excellent catalyst for synthesizing butanone 1,2-propanediol ketal and the product yield can reach over 82.7%.
