Title:

SOLID CATALYST FOR DEHYDRATION OF SUGAR ALCOHOL AND METHOD FOR PREPARING DIANHYDROSUGAR ALCOHOL USING SAID CATALYST

Document Type and Number:

WIPO Patent Application WO/2016/009607

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a solid catalyst capable of achieving high selectivity and high yield for isosorbide, preferably at the same time, in a dehydration reaction by which dianhydrosugar alcohol is obtained from sugar alcohol, particularly, in a dehydration reaction by which isosorbide is obtained from sorbitol. The abovementioned problem is solved by a solid catalyst for a dehydration reaction for preparing dianhydrosugar alcohol from sugar alcohol, said catalyst including an acidic β-zeolite having an atomic composition ratio of Si to Al (Si/Al) of more than 20.
