固体超强酸SO_4^(2-)/TiO_2-Fe_2O_3催化合成乳酸丁酯

The synthesis of nAbutyl lactate catalyzed by the compoAsite solid superacid SO_4^(2-)/TiO_2AFe_2O_3

采用共沉淀法制备了复合型固体超强酸 SO2 - 4/ Ti O2 -Fe2 O3,并将其用于催化乳酸与正丁醇的酯化反应。其催化活性和稳定性都优于单氧化物固体超强酸。

The composite solid superacid SO 2- 4/TiO 2-Fe 2O 3 was used as catalyst for the esterification of n—butyllactate.The suitable conditions have been found.The es—terification rate was 95.3%。
