| Abstract |
This research studied dehydration of sorbitol in aqueous solution to isosorbide over heterogeneous catalysts
(Amberlyst-15, Purolite CT269, and H-beta) and a homogeneous catalyst (sulfuric acid). The dehydration of sorbitol
was carried out in a high-pressure reactor under a nitrogen gas atmosphere at a fixed initial pressure of 2 MPa.
It was found that the Purolite CT269 catalyst gave the highest sorbitol conversion of 100% and an isosorbide
selectivity of 42% after 6 h at 453 K. The results showed that an increase in the reaction temperature gave rise
to sorbitol conversion. However, the solid - compound was formed during the reaction at high temperature by
polymerization of the product. The high acidity could catalyze the dehydration process; however, strong acid such
as sulfuric acid gave low selectivity to isosorbide. Thus, the acidity of the catalyst plays a vital role in catalytic
performance for the sorbitol dehydration to isosorbide |
