|Title:||METHOD FOR PRODUCING ANHYDROSUGAR ALCOHOL BY HIGH-PRESSURE REACTION|
The present invention relates to a method for producing an anhydrosugar alcohol by dehydrating a sugar alcohol at a high pressure in the presence of a catalyst being capable of inhibiting a side reaction at a high temperature and having weaker acid properties than conventional sulfuric acid catalysts. According to the present invention, an anhydrosugar alcohol can be produced in a yield similar to that obtained by a decompression reaction.
