| Abstract: | Magnetic solid superacids SO4^2-/ZrO2 was prepared by chemical modificating on solid superacids. It was used as catalyst in the esterification reaction. The yield of esterification achieved 95.6 % with lactic acid 0. lmol, isoamyl alcohol 0.25mol, magnetic solid superacids 1.7g and reaction tiem 2.5h. The catalyst could be isolated from other matters by its magnetism. And the recycle percentage was 84.5 %. |
