Zusammenfassung:	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. La présente invention concerne un procédé de production d'un alcool de sucre anhydre par déshydratation d'un alcool de sucre à pression élevée en présence d'un catalyseur capable d'inhiber une réaction secondaire à température élevée et présentant des propriétés acides plus faibles que les catalyseurs d'acide sulfurique classiques. Selon la présente invention, un alcool de sucre anhydre peut être produit avec un rendement similaire à celui obtenu par une réaction de décompression. 본 발명은 기존의 황산 촉매보다 산 특성이 약하고 고온에서 부반응을 억제할 수 있는 촉매의 존재하에 고압조건에서 당 알코올을 탈수시켜 무수당 알코올을 제조하는 방법에 관한 것이다. 본 발명에 따르면, 감압 반응과 유사한 수준의 수율로 무수당 알코올을 제조할 수 있다.
