Abstract: 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.

Key words: microwave irradiation, linalool, acetylation, linalyl acetate
