摘　　要：采用把 Zr O2 附载在 AL2 O3 表面较共沉淀能制得的 SO2 -/ Zr O2 _ Al2 O3 催化剂具有更好的催化活性 .经催化合成 DOP实验 ,酯化率在 99%以上 ,选择性为 96- 98% .SEM、XRD及 IR分析表明 ,SO42 -/ Zr O2 - AL2 O3 具有固体超强酸的光谱特征 .呈一定晶态的催化剂较无定形催化剂催化活性更好 .the catalyst SO 2- 4/ZrO 2 Al 2O 3 Prepared by zirconirm dioxide attached to the surface of Al 2O 3 has higher catalytic activity than that prepared by coprecipitation method.The catalytic activity for the synthesis of dioctyi phthalate was studied and the resuits show that the esterification rate reaches as high as 99% and the selectivity is 96-98%.The SEM,XRD and IR analyses indi-cate that the catalyst has catalyst has spectral characteristics of solid superacid.In addition,the crystalline state catalyst is more activated than non-crystalline catalyat.
