Abstract:
A water pretreatment method was used to evaluate the water-resistant stability of SO2-4/TiO2 solid superacid prepared by calcination under different temperatures. The structural properties of samples were characterized by the X-ray diffraction(XRD), NH3-TPD, fourier transform-infrared(FT-IR)spectroscopy, thermogravimetric(TG)analysis, and BET surface area analysis. The results showed that, when the calcination temperature did not exceed 500 ℃, the obtained SO2-4/TiO2 solid superacid had similar esterification performances. However, the pore structure of solid superacid collapsed and its SO2-4 content decreased when the calcination temperature exceeded 600 ℃. In this case, the esterification performance of the solid superacid was poor. After the water pretreatment, the esterification performances of all solid superacids descended, which was mainly attributed to the removal of SO2-4 and the decrease of acid amount. In a comparison, SO2-4/TiO2 solid superacid prepared at a calcination temperature of 400 ℃ had the optimum water-resistant stability.
