| Abstract: | Isoamyl acetate was synthesized with Ionic liquid bmiml PTSA as solvent and catalyst, and effect on the reaction was studied. The optimized condition was obtained as follows： usage of bmim ] PTSA 15 mL, mole ratio of alcohol to acid 1.5 ： 1.0, and reaction for 2 h, with the esterification rate of 92.2%. The Ionic liquid could be purified easily and use repeatedly. |
