Study on Synthesis of Linalyl Acetate under Microwave Irradiation

The technology of synthesizing linalyl acetate had been studied by using the method of interval microwave irradiation.The results showed that the optimized conditions were as follows: the ratio of acetic anhydride to linalool was 2.5∶1,4 % K2CO3 was used as catalyst(based on linalool weight) under 100 W microwave,and the irradiation time was 5 h.The conversion of linalool was 76.71 % and the yield of linalyl acetate was 61.48 % under optimum conditions.Compared with normal methods,the technology needs shorter time and cheaper catalyst to achieve higher productivity of linalyl acetate.
