纳米固体超酸SO_4^(2-)/Fe_2O_3的研究与应用

Studies and application on SO_4^(2-)/ Fe_2O_3 nanosolid superacid systems

采用纳米化学制备技术合成了新型的纳米固体超酸SO2 -4/Fe2 O3 .它对醋酸和脂肪醇的酯化反应有良好的催化作用 ,并具有耐水性强、可重复使用、再生容易。

The new nanosolid superacid SO 2- 4/ Fe 2O 3 is prepared by using nanometer chemical technology.They are active for esterification of acetic acid with alcohol.This kind of nanosolid superacid has many advantages.Such as being able to use several times,recovery very easy,high water resistibility,less corrosion for te equipment and less pollution to the environment.So it is a solid catalyst that has applied prospect.
