| 摘 要： | 用锐钛型纳米TiO2制备了纳米级SO42-/TiO2固体超强酸,考查了焙烧温度对酸强度、比表面积、红外光谱及其催化活性的影响.结果显示该催化剂在450℃焙烧3 h,可以形成纳米级SO42-/TiO2固体超强酸的结构.用该催化剂催化乙酸和丁醇酯化反应可使酯化率达到98.4%. |
| 关 键 词： | 纳米TiO2 SO42-/TiO2 固体超强酸 酯化反应 |

| Abstract: | The nanograde SO~(2-)_(4)/TiO_(2) solid superacid was prepared by anatase nano-titania.The acid strength,specific surface area,IR spectroscopy and catalytic activity of the samples under different calcination temperature were analyzed.It was shown that nanograde SO~(2-)_(4)/TiO_(2) solid superacid could be formed when calcined at 450 ℃ for 3 h.The title superacid could catalyze the esterification reaction of acetic acid and n-butanol to give yield of 98.4 %. |
| Keywords: | nanograde TiO_2 SO_4~(2-)/TiO_2 solid superacid esterification reaction |
