Fructone was synthesized from ethyl acetoacetate and glycol in the presence of copper benzene sulfonate. The influence factors of the synthesis were discussed and the best conditions were found out. The optimum conditions were:molar ratio of ethyl acetoacetate to glycol was 1∶1.5 ,the quantity of catalyst adding was equal to 1.5%feed stock , and the reaction time was 60min. Copper benzene sulfo-nate was an excellent catalyst for synthesis of fructone, the yield could reach over 82.7%.
