【Abstract】 A new solid acid catalyst SO42-MoO3TiO2 was prepared.FT-IR data had indicted that the surface of the catalyst had strong acidic centers.FTIR spectra of pyridine absorbed on the surface showed that the catalyst had Bronsted acid site.The catalyst had high catalytic activity and excellent selectivity in esterification,acetalation and ketal formation as well as no corrosion to the facilities.The catalyst was an enviormentally friendly catalyst.更多还原
