Abstract

Liquid-phase dehydration of sorbitol to isosorbide has been carried out for the first time with sulfated titania (S-TiO₂) catalyst and its performance was compared with the catalytic activity of titania (TiO₂) to investigate the effect of sulfation. The catalyst was produced in situ from titanium isopropoxide and sulfuric acid as the source for TiO₂ and the sulfate group, respectively. The optimum reaction conditions e.g. temperature, catalyst dosage and reaction time were investigated for the dehydration reaction using the sulfated catalyst. As a result, S-TiO₂, which contains sulfate acidic sites, is a promising catalyst for liquid-phase dehydration of sorbitol to isosorbide.
