摘　　要：A novel type of rare earth promoted solid super acid catalyst,S2O82-/ZrO2-SiO2-Sm2O3,was prepared by a special precipitation method,and ammonia persulfate was used as promoter instead of sulfuric acid.The catalysts were characterized by XRD,TG-DTA etc.The XRD patterns of the catalysts belong to amorphous.There were much more B acid on the surface of the catalysts.It was found that the addition of rare earth could enhance the activity of catalyst significantly,the conversion of acetic acid is 99.4% in the esterification reaction by the acetic acid with the 1-butanol.A novel type of rare earth promoted solid super acid catalyst, S2O8^2-/ZrO2-SiO2-Sm2O3, was prepared by a special precipitation method, and ammonia persulfate was used as promoter instead of sulfuric acid.
