| Zusammenfassung: | The present invention relates to a method of producing anhydrosugar alcohol by dehydrating sugar alcohol at high pressure in the presence of a catalyst which is less acidic than a conventional sulfuric acid catalyst and which can suppress side reactions at high temperature. According to the present invention, anhydrosugar alcohol can be produced in a yield similar to that in a vacuum reaction. |
