摘　　要：The titanium sulfate catalyst was prepared by calcination at 400～500 ℃. IR spectra of pyridine adsorption showed the presence of Brnsted acid sites on its surface. The catalysts had good activity in ketalization between cyclohexanone and 1,2-propanediol with yield being 89% in reaction conditions:molar ratio of cyclohexanone to 1,2-propanediol 1∶1 3, catalyst amount 4% based on the mass of cyclohexanone, 140 ℃ and 50～75 min. In esterification of succinic acid with butanol the yield of dibutyl succinate was 97%. The catalyst could be reused through regeneration.
