Abstract
Terpinyl acetate was synthesized from terpineol and acetic anhydride using SnCl_4·5H_2O as a catalyst.The optimal reaction conditions at 30 ℃ for 4 h were as follows: terpineol was 50 mmol,n(terpineol) ∶n(acetic anhydride) was 1.0 ∶1.4,SnCl_4·5H_2O was 250 mg.The conversion of terpineol was 94.1% and the selectivity of terpinyl acetate was 93.3% under the optimal reaction conditions.
