摘　　要：选择TRPO-煤油/HCl-Zr(Ⅳ)三相萃取体系中负载Zr(Ⅳ)量最大的第三相作为模板,用沉淀反萃和硫酸浸渍的方法,成功地制备了介孔SO42-/Zr O2固体超强酸催化剂,并用TEM和IR进行了表征。研究其在丙烯酸正丁酯合成中的催化性能和浸渍剂硫酸的浓度对其活性的影响,发现其具有良好的催化活性,当浸渍剂硫酸的浓度为0.1mol/L时,丙烯酸正丁酯的酯化率可达到88.7%。The third phase formed in TRPO -kerosene/HCl - Zr（ 1V ）extraction system is used as the template to prepare mesoporous SO4^2-/ZrO2solid acid catalyst By using the method of precipitation stripping and sulfuric acid soaking. TEM and IR are adopted for the characterization of the SO4^2-/ZrO2solld acid catalyst. It is used as the catalyst of acrylicacid n -butylester and demonstrates the good catalytic activity. This artieal studied The influence of impregnating agent concentration to the percentage of the conversion of esterification and discovered that It is suitable that the density of the sulfuric acid take 0. lmol/L and the esterifieation rate may achieve 88.7%.
