Synthesis of isoamyl acetate with composite solid super acid catalyst

SO42-/Fe2O3/ZnO/ZrO2 Composite solid superacid catalyst has been prepared and applied.Isoamyl acetate was synthesized from acetic acid and isopentyl alcohol in the presence of this composite solid superacid.The influence of initial rate with molar ratio of reagents,the reaction temperature,and the reaction time,the amount of catalyst and different calcinations temperature of catalyst were studied.The results showed that the appropriate conditions of synthesis of isoamyl acetate as follows:reaction time was 50 min at 120 ℃,the mole ratio of isoamyl alcohol to acetic acid was 2∶ 1,the catalyst was equal to 7% by the mass of acetic acid,the calcinated temperature was 650 ℃.
