AlCl_3/D001固体酸的制备及在苹果酯合成中的应用

The Proparation of Solid Acid AlCl_3/D001 and Its Application in Synthesis of Fructone

AlCl3/D001为催化剂 ,催化乙酰乙酸乙酯和乙二醇的反应合成苹果酯。反应条件 :1.0mol乙酰乙酸乙酯 ,1.6mol乙二醇 ,150ml苯 ,7gAlCl3/D001 ,反应3h ,苹果酯收率82.3 %。

Frutone is synthesized by reaction of ethyl acetyl acetate and ethyleneglycol with AlCl3/D001 as the catalyst. The optimum conditions are found as follows:the ratio of ethyl acetyl acetate to ethyleneglycol to benzene to AlCl3/D001 is 1.0 mol to 1.6mol to 7g for 3 hours.With these conditions, the yield reaches 82.3%.
