摘要
采用硅钨酸铝作催化剂 ,以乙酰乙酸乙酯和 1 ,2 丙二醇为原料合成草莓酯。优化的反应条件为 :0 2mol乙酰乙酸乙酯 ,0 2mol1 ,2 丙二醇 ,40ml环己烷 ,0 3 g硅钨酸铝 ,反应 3 5h ,草莓酯收率达 81 6%。
Fraistone was synthesized with reaction of Ehyl Acetyl acetate and 1,2 Propanediol, by aluminnm silicolungstie as catatlyst. The optimum conditions are follows: the ratio of ethyl acetate, 1,2 Propanediol, Cyclohexane,Aluminnm Silicolungstie is 0.2?mol:0.2?mol:40?ml:0.3?g, reaction for 3.5 hours.The yield reaches 81.6%. The product was characterized by the physical and chemical character, and spectra.
