| Abstract: | 2-Ethylhexyl salicylate was synthesized from 2-ethylhexanol and salicylic acid with sodium hydrogen sulfate as catalyst by use of microwave radiation. The experimental results showed that the optimum conditions were as follows: 0. 05 tool salicylic acid was added, the molar ratio of salicylic acid to 2-ethylhexanol was 1 : 4, the dosage of catalyst was 6.93wt% of the reagent, the microwave power was 360 W, the reaction time was 35 min, and no water-carrying reagent was used. Under the above conditions, the yield of 2-ethlyhexyl salicylate could reach 89. 33%. The synthesized product was confirmed by refractive index, IR, UV and GC/MS. |
