摘要： A process is described for continuous production of anhydrosugar alcohol by continuous introducing of sugar alcohols and/or monoanhydrosugar alcohols into a reaction vessel and dehydration in the presence of an acid catalyst and solvent in which the resultant reaction product is soluble. Water and the solvent having the dissolved reaction product are each cointinuously removed from the reaction vessel. The reaction product is separated from the removed solvent and the product is optionally purified to a purity of 99.0% the solvent is recycled in the reaction vessel.
摘要翻译： 描述了通过将糖醇和/或单乙二醇糖连续引入反应容器中并在酸催化剂和其中所得反应产物可溶的溶剂的存在下进行脱水来连续生产脱水葡萄糖醇的方法。 水和具有溶解的反应产物的溶剂各自从反应容器中连续地除去。 将反应产物与去除的溶剂分离，任选地将产物纯化至99.0％的纯度，将溶剂在反应容器中再循环。
