Fructone was synthesized from ethyl acetoacetate and glycol catalyzed by methanesulfonate. The factors influencing the synthesis were discussed and best conditions were found out. The optimal process conditions were obtained as follows: the molar ratio of the reactants wasn(ethyl acetoacetate):n(glycol)=1:1.5; the amount of calcium methanesulfonate was 0.6 g and water carrying agent was 10 mL; reaction time was 1.5 h. The yield was 86.53%. The results showed that calcium methanesulfonate had high catalytic activition for the synthesis of fructone.
