磁性固体超强酸ZrO_2/SO_4^(2-)的制备及催化性能研究

Preparation of Magnetic Solid Superacids ZrO_2/SO_4^(2-) and Research of Its Catalysis for Esterification

在不同条件下制出磁性固体超强酸ZrO2/SO42-催化剂,应用于乙酸和正丁醇的酯化反应中.结果表明,在Fe∶Zr的物质的量比为1∶0.8,硫酸浓度为1.2 mol/L,焙烧温度为500℃时,对酯化反应的催化性能最好.

Magnetic solid superacid ZrO2/SO4^2- is prepared under different conditions and used as catalyst in the synthesis of Butyl acetate. It is found that when Fe ：Zr proportion is 1：0.8 （mol） , sulphurie acid concentration is 1.2 mol/L,temperature is 500℃ , the catalyst activity is the best.
