The nanometer-sized SO42-/TiO2,SO42-/ZrO2 and SO42-/Fe2O3 solid superacid have been prepared and their esterification activity for n-butanol with acetic acid has been examined. The activity order of them is SO42-/TiO2>SO42-/ZrO2>SO42-/Fe2O3.

• 制备了纳米级SO42 -/TiO2、SO42 -/ZrO2、SO42 -/Fe2O3 固体超强酸催化剂 ,考察了其对正丁醇和乙酸的酯化活性 ,表明SO42 -/TiO2 的活性最好 ,SO42 -/ZrO2 次之 ,SO42 -/Fe2O3 较差
