- W2367450253 abstract "SO2-4/ TiO2solid acid catalyst was prepared by hydrothermal method,the catalytic performance was evaluated by the esterification reaction of butanol with acetic acid. And its structural characteristics and catalytic stability were characterized by X-ray diffraction,infrared spectroscopy and thermogravimetry. The results indicated that the SO2-4/ TiO2solid acid catalyst has nano-scale particles,pure anatase phase and high thermal stability. Under the optimal preparation and reaction conditions, hydrothermal temperature of 150 ℃,sulfate concentration of 1 mol / L,hydrothermal time of 24 h,and m( catalyst) = 0. 5 g,the catalyst shows a n-butanol conversion of 82. 09% with a high selectivity for butyl acetate of 100 %. The results also indicated that a severe leaching of SO2-4/ TiO2solid acid catalyst was observed at the former three times,but its catalytic activity remained stable later. The catalyst exhibit excellent catalytic activity and reuability." @default.
