Title:
METHOD FOR PRODUCING ANHYDROUS SUGAR ALCOHOL USING AZEOTROPIC DISTILLATION
Document Type and Number:
WIPO Patent Application WO/2016/060399
Kind Code:
A3
Abstract:
The present invention relates to a method for producing an anhydrous sugar alcohol and, more specifically, to a method for producing an anhydrous sugar alcohol using a solvent containing at least two components, which have a large difference in the boiling point and form an azeotrope together with water at normal pressure. The method for producing an anhydrous sugar alcohol according to the present invention can increase the yield of the anhydrous sugar alcohol by efficiently adjusting a reaction temperature using the solvent containing at least two components, which have a large difference in the boiling point and form an azeotrope together with water at normal pressure.
