    • The invention includes a method of dehydration of a sugar using a dehydration catalyst and a co-catalyst within a reactor. A sugar is introduced and H 2 is flowed through the reactor at a pressure of less than or equal to about 300 psig to convert at least some of the sugar into an anhydrosugar product. The invention includes a process for producing isosorbide. A starting material comprising sorbitol is flowed into a reactor. H 2 is counter flowed through the reactor. The starting material is exposed to a catalyst in the presence of a co- catalyst which comprises at least one metal. The exposing is conducted at a hydrogen pressure of less than or equal to 300 psig within the reactor and the hydrogen removes at least some of any water present during the exposing and inhibits formation of colored byproducts.

    • The invention includes a method of treating a solid acid catalyst. After exposing the catalyst to a mixture containing a sugar alcohol, the catalyst is washed with an organic solvent and is then exposed to a second reaction mixture. The invention includes a process for production of anhydrosugar alcohol. A solid acid catalyst is provided to convert sugar alcohol in a first sample to an anhydrosugar alcohol. The catalyst is then washed with an organic solvent and is subsequently utilized to expose a second sample. The invention includes a method for selective production of an anhydrosugar. A solid acid catalyst is provided within a reactor and anhydrosugar alcohol is formed by flowing a starting sugar alcohol into the reactor. The acid catalyst is then exposed to an organic solvent which allows a greater amount of additional anhydrosugar to be produced than would occur without exposing the acid catalyst to the organic solvent.
    • 本发明包括一种处理固体酸催化剂的方法。 在将催化剂暴露于含有糖醇的混合物之后,将催化剂用有机溶剂洗涤,然后暴露于第二反应混合物。 本发明包括生产脱水葡萄糖醇的方法。 提供固体酸催化剂以将第一样品中的糖醇转化成脱水葡萄糖醇。 然后将催化剂用有机溶剂洗涤,随后用于暴露第二个样品。 本发明包括选择性生产脱水糖的方法。 在反应器内提供固体酸催化剂,并通过将起始糖醇流入反应器而形成脱水葡萄糖醇。 然后将酸催化剂暴露于有机溶剂,其允许比不会将酸催化剂暴露于有机溶剂的情况下产生更多量的额外的脱水糖。
