The Catalytic Activity of Titanium Sulfate in Ketalization and Esterificatio
Abstract:
The titanium sulfate catalyst was prepared by calcination at 400~500℃.IR spectra of pyridine adsorption showed the presence of Brönsted 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.
