Synthesis of Cyclohexyl Propionate Catalyzed by Ferric Sulfate Hydrate Under Microwave Irradiation

Cyclohexyl Propionate was directly synthesized by propionic acid and cyclohexanol with ferric sulfate hydrate as the catalyst under microwave irradiation.The effects of microwave irradiation power,irradiation time,reactant ratio,amount of catalyst and amount of watercarrying agent on the yield of cyclohexyl propionate were systematically studied.Research results showed that the optimum reaction conditions were as follows:microwave irradiation power was 700 W,fixed amount of propionic acid was 0.05 mol,the ratio of cyclohexanol to propionic acid was 3∶1,the amount of catalysts was 1.5 g,and cyclohexane as the water-carrying agent was 6 mL,after 30 min reaction,the yield of cyclohexyl propionate reached 94.4%.
