| Abstract: | The solid super acid heterogeneous catalyst SO_4~(2-)/ZrO2-TiO2 was synthesized and was used catalytic for the esterification of iso-butanol(IBA) with methacrylic acid (MAA) in the liquid-solid system. The effects of reaction conditions was investigated. The results showed that the catalyst has high catalytic activity. The yield was 86.4%, the purity of the product was over 98%. |
