  A process is disclosed for converting polysaccharide-containing biomass material to platform chemicals. The process comprises dissolving the polysaccharides in an inorganic molten salt hydrate, converting the polysaccharides to monosaccharides, and converting the monosaccharides to platform chemicals that are easily separable from the inorganic molten salt hydrate. The process comprises a dehydration step in which sugar alcohols are converted to the corresponding (di) anhydro sugars. The dehydration step is carried out in the substantial absence of transition metal salts.

  A method for preparing a dialkyloxydianhyrohexitol (dimethylisosorbide) composition by etherification of dianhydrohexitol (isosorbide). The aim is to achieve a “clean” method that avoids the use of a methylation agent such as dimethyl sulfate or methyl chloride, which generates stoechiometric quantities of salts, or expensive dialkyl-carbonates, wherein only one of the two methyl groups participates in the preparation of mixed isosorbide ethers. The method involves using at least one O-alkylation agent and a catalyst including an acid or an acid salt, preferably a catalyst having Lewis or BrØnsted acid properties. A device for carrying out the method wherein the device includes a vaporization oven and a reaction oven is also described.

  一种制备二烷氧基二环己基醇（二甲基异山梨醇）组合物的方法，通过对二环己基醇（山梨醇）进行醚化反应。其目的是实现一种“清洁”方法，避免使用甲基化试剂，例如二甲基硫酸酯或氯化甲基，这些试剂会产生化学量的盐或昂贵的二烷基碳酸酯，其中仅有一个甲基参与混合山梨醇醚的制备。该方法涉及使用至少一种O-烷基化试剂和催化剂，包括酸或酸盐，最好是具有路易斯或布朗斯特德酸性质的催化剂。还描述了一种用于执行该方法的装置，其中该装置包括一个蒸发炉和一个反应炉。

  Diesel cycle fuel compositions are described containing at least one dianhydrohexitol compound according to the general formula 2 and/or its derived hydrocarbyl ethers or nitric ethers compounds, where the R′ and R″ substituents are both H or one or both of R′ and R″ is alkyl, cycloalkyl or phenyl, or one or both are —NO 2 . A preferred fuel composition is that containing dimethyl isosorbide (DMI) added or not of isosorbide dinitrate (ISDN) as ignition improver. The dianhydrohexitols compounds form compositions with at least one of the components selected among petroleum-derived diesel fuel, biodiesel, ethanol and water. The mixture of DMI and ISDN has excellent cetane number (IQT). Still, the oxygenated nature of the dianhydrohexitols and related compounds of the fuel compositions inhibits soot formation upon burning of the said Diesel cycle fuel compositions.

  柴油循环燃料组分的描述包含至少一种二环己糖醇化合物，其符合通式2和/或其衍生的烃基醚或硝基醚化合物，其中R'和R"取代基均为氢，或者R'和R"中的一个或两个是烷基、环烷基或苯基，或者一个或两个是-NO2。首选的燃料组分是含有二甲基异山梨醇(DMI)的组分，加入或不加入异山梨醇二硝酸酯(ISDN)作为着火改进剂。二环己糖醇化合物与石油衍生柴油燃料、生物柴油、乙醇和水中的至少一种组分形成组合物。DMI和ISDN的混合物具有优异的十六烷值(IQT)。然而，燃料组分中二环己糖醇和相关化合物的含氧性质抑制了燃烧时的烟灰形成。
