| Abstract: | Fe2(SO4)3 solution was loaded on molecular sieve by impregnation and SO42-/Fe2O3 solid super acids based on molecular sieve was prepared by calcination.The effect of mass ratio of molecular sieve and Fe2(SO4)3,calcination time and calcination temperature on esterification performance were researched by referring to butyl acetate esterification reaction,obtained the optimum preparation condition the rate of mass is 5∶2,the calcination temperature is 550℃ and the calcination time is 4 h.The acid strength H0≤12.7 by indicator method is confirmed solid super acid. |
