| Abstract: | Magnetic solid superacids SO42-- /ZrO2 was prepared by chemical modificating on solid superacids. It was used as catalyst in the esterification reaction. The yield of esterification achieved 93.7%with isoamyl alcohol 0. 4mol, acetic acid 0. 2mol, magnetic solid superacids 1. 2g and reaction times 2. Oh. The catalyst could be isolated from other matters by its magnetism. And the recycle percentage was 84.3 % . |
