采用稀土改性ＳＯ２－４／ＴｉＯ２固体超强酸催化合成水杨酸异戊酯．结果表明，该种催化剂不但具有一般超强酸的性能，而且催化活性高，制备工艺简便．讨论了该种催化剂的制备条件以及反应条件对酯化反应的影响．
Synthesis of isoamyl salicylate catalyzed by rare earth modified SO2-4 / TiO2 solid superacid. The results show that the catalyst not only has the properties of general superacid, but also has high catalytic activity and simple preparation process. The preparation conditions of the catalyst and the influence of the reaction conditions on the esterification were discussed.
