| Abstract: | Isopropyl salicylate was synthesized with isopropyl alcohol and salicylic acid as meterials and solid superacid SO 2- _4/TiO_2/La 3+ as catalyst.The factors that had influence on the reaction were investigated.The optimum reaction conditions are as follow(for 0.1mol of salicylic acid):ratio of isopropyl alcohol to salicylic acid is 3.0mol:1.0mol,catalyst amount is 1.5g,reaction time is 3.5h and temperature is reflux temperature.The yield under the optimum con-ditions was up to 94.8% and the catalyst could be used once more. |
