    • The invention includes methods of producing dianhydrosugars. A polyol is reacted in the presence of a first catalyst to form a monocyclic sugar. The monocyclic sugar is transferred to a second reactor where it is converted to a dianhydrosugar alcohol in the presence of a second catalyst. The invention includes a process of forming isosorbide. An initial reaction is conducted at a first temperature in the presence of a solid acid catalyst. The initial reaction involves reacting sorbitol to produce 1,4-sorbitan, 3,6-sorbitan, 2,5-mannitan and 2,5-iditan. Utilizing a second temperature, the 1,4-sorbitan and 3,6-sorbitan are converted to isosorbide. The invention includes a method of purifying isosorbide from a mixture containing isosorbide and at least one additional component. A first distillation removes a first portion of the isosorbide from the mixture. A second distillation is then conducted at a higher temperature to remove a second portion of isosorbide from the mixture.
    • 本发明包括生产二脱水甘油糖的方法。 多元醇在第一催化剂存在下反应形成单环糖。 将单环糖转移到第二反应器中,在第二反应器中,在第二催化剂的存在下将其转化为二脱水甘油醇。 本发明包括形成异山梨醇的方法。 在固体酸催化剂存在下,在第一温度下进行初始反应。 初始反应包括使山梨醇反应生成1,4-脱水山梨糖醇,3,6-脱水山梨糖醇,2,5-甘露聚糖和2,5-己烷。 利用第二温度,将1,4-脱水山梨醇和3,6-脱水山梨醇转化为异山梨醇。 本发明包括从含有异山梨醇和至少一种另外的组分的混合物中纯化异山梨醇的方法。 第一蒸馏从混合物中除去第一部分的异山梨醇。 然后在较高温度下进行第二次蒸馏以从混合物中除去第二部分的异山梨醇。

    • 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.
