    • The present invention relates to a technique for producing a high-purity anhydrosugar alcohol using sugar hydride as a raw material and, more specifically, to a method for producing a high-purity anhydrosugar alcohol by adding acid into a sugar hydride (e.g. hexitol) to convert the sugar hydride into an anhydrosugar alcohol, distilling the result solution of the conversion, and crystallizing the result solution of the distillation in a solvent to produce an anhydrosugar alcohol. According to the method for producing high-purity anhydrosugar alcohol of the present invention, a solvent of crystallization is removed from a mother liquor generated in the crystallization process and the output is injected with the result solution of distillation and the result solution of the conversion in the distillation process to raise the total yield of the anhydrosugar alcohol; the liquidity of a distillate is enhanced to increase distillation efficiency, further to reduce the amount of waste and costs for processing, so that the technique of the present invention can produce an anhydrosugar alcohol with low costs and high efficiency.
