Abstract
The present invention relates to a method for producing an anhydrosugar alcohol and, more specifically, to a method for producing an anhydrosugar alcohol which, when the step of subjecting a hydrogenated sugar to a dehydration reaction in a reactor so as to convert same to an anhydrosugar alcohol is performed, allows the hydrogenated sugar to be continuously introduced into the reactor and the produced anhydrosugar alcohol to be continuously discharged out of the reactor while the dehydration reaction is carried out, also prevents a reaction mixture from circulating inside and outside the reactor while the dehydration reaction is carried out, and thereby can significantly improve production efficiency compared with a conventional process adopting a batch or semi-batch-type dehydration reaction and thus can be appropriately applied particularly to a large-scale anhydrosugar alcohol production process.
