Effects of different reaction conditions on the synthesis of terpinyl acetate

Yongmei Zhang

The main properties of terpinyl acetate have been introduced. Different catalysts that consist of solid superacid SO4 2- /ZnO-TiO2, SnCl4 · 5 H2 O, H3PO4/[C4 mim]BF4, functional polyether ionic liquid (1-(3-sulfonic group)propyl -3 -polyoxyethyleneimi - dazole dihydrogen phosphate ([HS03 - (CH2)3 - im- (CH2CH2O)nH]H2PO4)) and SO2- 4 /SnO2 -CeO2 have also been introduced. Effects of different reaction conditions such as the amount of catalyst, the molar ratio of terpineol to acetic anhydridel, the reaction temperature, the reaction time and reusable catalyst times are discussed. The optimum amount of catalyst, the molar ratio of terpineol to acetic anhydridel, the reaction temperature, the reaction time and reusable catalyst times are beneficial to improve the yield of terpinyl acetate.
