采用浸渍法,将几种锌盐载于无机载体上,制得固体酸催化剂,进行非均相催化松香酯化反应。讨论浸渍液浓度,活化温度、催化剂的孔容、形状、表面酸强度对催化剂活性的影响。
Using impregnation method, several zinc salts are carried on an inorganic carrier to prepare a solid acid catalyst for heterogeneous catalysis rosin esterification reaction. The effects of impregnation solution concentration, activation temperature, pore volume, shape and surface acidity on the catalytic activity were discussed.
