Synthesis of Isoamyl Acetate Using 732 Cation Exchange Resin Catalyst

Isoamyl acetate was synthesized from acetic acid and isoamyl alcohol with 732 cation exchange resin as the catalyst, cyclohexane as water-carrying agent. The effects of the dosage of catalyst, raw material ratio, reaction time and reaction temperature on the yield were investigated. The experiment results showed that the preferable reaction conditions were as follows, when the amount of isoamyl alcohol was 0.1 mol, the molar ratio of isoamyl alcohol to acetic acid was 1:1.7, the amount of catalyst was 0.9 g, the amount of the water-carrying agent was 6 mL, through reacting 2 h, the yield of isoamyl acetate reached 54.6%.The catalytic efficiency started to decrease after 6 cycles of usage.
