Title:
A METHOD FOR PREPARATION OF ANHYDROSUGAR ALCOHOLS
Document Type and Number:
WIPO Patent Application WO/2012/165676
Kind Code:
A1
Abstract:
Disclosed is a method for the preparation of an anhydrosugar alcohol using a starch-derived hexitol such as sorbitol or mannitol. Anhydrosugar alcohol is in the form of a diol having two hydroxyl groups in the molecule thereof and has a very high utility value as a physical property modifier which can be used primarily in plastics. Representative examples of anhydrosugar alcohols include isosorbide and isomannide. These anhydrosugar alcohols are capable of increasing a glass transition temperature of and improving strength of PET, polyesters, polycarbonates, etc., and are therefore highly valuable as biodegradable environmentally-friendly bioplastics.
