Synthesis of Linalyl Acetate Catalyzed by Solid Acid HMCM-41

Linalyl acetate is a kind of important perfume in the formation of advanced perfumery compounds. Chemical routes for the synthesis of linalyl acetate mainly involve acidic catalysis from linalool or the Williamson method starting with halohydrocarbon. Besides the unfriendliness of the reaction systems, low synthetic yields were obtained, which can be due to many secondary reactions and their by-products. In this paper, mesoporous molecular sieve HMCM-41 is found to be a remarkably effective and regenerable heterogeneous solid-acid catalyst for the catalyzed synthesis of linalyl acetate from linalool and acetic anhydride. Experimental parameters were discussed. The transforming ratio of linalool is about 99%, the yield of linalyl acetate is above 50%.
