摘要： An enhanced process for the production of a dianhydrosugar, such as isosorbide, from the corresponding sugar alcohol is described. The sugar alcohol is combined with an acid catalyst and reacted at elevated temperatures and at atmospheric pressure, eliminating the need for a vacuum. High selectivity and yields are achieved.

摘要翻译： 描述了用于从相应的糖醇制备二脱水菌糖如异山梨醇的增强方法。 糖醇与酸催化剂结合，并在升高的温度和大气压下反应，消除了对真空的需要。 实现了高选择性和收率。
