Abstract
The present invention relates to a method for producing anhydrosugar alcohol, and more particularly to a method of producing anhydrosugar alcohol using a solvent including at least two components that form an azeotrope with water at atmospheric pressure and that have significantly different boiling points. The method for producing anhydrosugar alcohol according to the present invention can increase the yield of anhydrosugar alcohol by efficiently controlling the reaction temperature by use of a solvent including at least two components that form an azeotrope with water at atmospheric pressure and that have significantly different boiling points.
