| Abstract: | Under the condition of microwave irradiation, iso - octyl salicylate was synthesized from salicylic acid and 2 -ethyl hexanol with nanometer solid superacid SO4^2-/Fe2O3 as catalyst. The optimal reaction conditions were obtained as follows： salicylic acid 0. 01 mol, 2 - ethyl hexanol 0. 03 mol, the dosage of catalyst was 41.4 mg, microwave power was 350 W,irradiation time was 15 min. The yield of the ester was 98.8% under the conditions. |
