固体超强酸SO_4^(2-)/T_iO_2催化合成三醋酸甘油酯

Synthesis of Glyceryl Triacetate Using Solid Superacid Catalyst SO_4^(2-)/TiO_2

试验用固体超强酸■催化醋酸和甘油合成三醋酸甘油酯。考察了催化剂活化温度与催化活性之间的关系，用正交试验法研究了反应因素对收率的影响，在最佳条件下，收率达89％。

A solid superacid is used as catalyst in the synthesis of glyceryl triacetae from glycerol and aretic arid,and the influence of a soid superacid on the reaction is studied.The reaction factors are analyzed with experiments of orthognal matrix.Under the optimum conditions,the yield could reach 89%.
