摘　　要：依据微乳理论,运用OP-10/环己烷/正丁醇微乳体系,制备出以硫酸锌为基体的固体超强酸S2O82-/ZnSO4-SnO2。以乙酸丁酯合成反应为探针反应,得出固体超强酸S2O82-/ZnSO4-SnO2制备的优化条件:m SnO2/m ZnO=30:70、陈化时间为24 h、浸渍液浓度2.0 mol·L-1、焙烧温度550℃、焙烧时间3.0 h,油相与水相体积比(R)=50︰100并对其进行了XRD、FTIR、TG-DTA、BET和SEM技术分析。The superacid catalyst S4O8^2-/ZnSO4-SnO2was prepared by microemulsion method in OP-10/n-butanol/cyclohexane system, on the basis of microemulsion theory. The catalytic performance of the prepared catalyst was evaluated by esterification of acetic acid and n-butanol. The optimal preparation condition of solid superacid S2O8^2-/ZnSO4-SnO2was showed as follow： msnO2/mznsO4 = 30 ： 70, aging time 24 h, impregnatal concentration 2.0 mol. L-1 , calcination temperature 550℃, calcination time 3.0 h ; The volume ratio of oil phase to water phase（R） = 50 ： 100. The physic-chemical properties of the materials were characterized by XRD,FT- IR,TG-DTA,BET and SEM techniques.
