| Abstract: | S2O82-/AI-Zn-Ce-O solid acid catalysts were synthesized by sol-gel.The structures and properties of the catalyst were characterized by means of infrared spectrum（IR）,X-ray powder diffraction（XRD）,thermogravimetric analysis-differential scanning calorimetry（TG/DSC） and scanning electron microscopy（SEM）.The catalytic activities and reusabilities for the synthesis of n-butyl acetate from acetic acid and n-butanol were investigated.Compared with S2O82-/AI-Zn-O solid acid catalyst, S2O82-/AI-Zn-Ce-O solid acid catalyst exhibited better stability with above 94%esterification efficiency even after being used repeatedly for five times. |
