摘　　要：以硫酸高铈铵为催化剂,通过乙酰乙酸乙酯分别与乙二醇和1,2-丙二醇反应合成了苹果酯-A和苹果酯-B,研究了催化剂等有关因素对产品收率的影响.实验表明,硫酸高铈铵是合成苹果酯-A和苹果酯-B的良好催化剂,在酯醇物质的量比为1∶1.65,催化剂用量为（0.8～1.0）g/0.1mol乙酰乙酸乙酯,环己烷10mL,反应时间3h的条件下,收率可达94.0%和92.1%.Fructone- A and Fructone- B was synthesized from ethyl acetoacetate and ethanediot or 1,2- propanediol using ammonium ceric sulfate as catalyst , The factors influencing the synthesis were discussed and best optimum conditions were found out, The molar ratio of ethyl acetoacetate to alcohol was 1 ; 1.65,the amount of catalyst was （0. 8-1. 0）g/0.1mol ethyl acetoacetate,the reaction time was 3h. Ammonium ceric sulfate is a good catalyst for synthesizing fructone-A and fructone-B,the yield can reach up to 94.0% and 92.1%.
