| Abstract: | The Synthesis of isoamyl salicylate and isooctyl salicylate was catalyzed by the rare-earth solid superacid SO4^2-La^3＋/TiO2 under microwave irradiation. The optimum condition of esterfication： microwave irradiation power was 420 W（350 W）, reacting time was 4 min（3 min）, solid superacid catalyst was 0.6 g（0.8 g）, n（salicylic acid） ： n（ isoamol（isooctol））=1 ： 3.0（1 ： 2.5） and the yield of salicylic acid was 94.8 %（92.6 %）. |
