Method of Producing Anhydrosugar Alcohol Using Steam

摘要

The present invention provides a method for producing anhydrosugar alcohol, including: feeding sugar alcohol into a reactor and performing a dehydration reaction of the fed sugar alcohol to produce anhydrosugar alcohol; and supplying steam to the reactor to evaporate the produced anhydrosugar alcohol. According to the present invention, anhydrosugar alcohol can be produced in a high yield by increasing the specific surface area of reaction mother liquor and reducing the partial pressure of the product.
