摘　　要：Solid acid ferric sulphate Fe2（SO4）3 was prepared and used for the study of the catalytic synthesis of iso-amyl propionate.The optimun reaction conditions were follows:the ratio of amount of substance n（iso-amylalcohol）:n（propionic acid）=1.5,the reaction time 2h,the catalyst quantity 1.5g,and dewatering solvent toluene 10ml.The yield was 97.2% under the optimum reaction conditions.The catalyst being of high catalytic activity for the esterification reactions was prepared very easily and could be used repeatedly.Solid acid ferric sulphate Fe_2(SO_4)_3 was prepared and used for the study of the catalytic synthesis of iso-amyl propionate.The optimun reaction conditions were follows:the ratio of amount of substance n(iso-amylalcohol):n(propionic acid)=1.5,the reaction time 2h,the catalyst quantity 1.5g,and dewatering solvent toluene 10ml.The yield was 97.2% under the optimum reaction conditions.The catalyst being of high catalytic activity for the esterification reactions was prepared very easily and could be used repeatedly.
