  • Method for the isomerisation of glucose into fructose
    Patent number: 9963477
    Abstract: The invention relates to a method for the isomerization of glucose into fructose in water in the presence of a solid base catalyst characterized by its reversibility of CO2 adsorption at a low temperature, the catalyst being a catalyst comprising at least one supported or non-supported lanthanide oxide or a molecular sieve based on silicon containing the organic template thereof. The invention also relates to a method for preparing HMF from glucose, comprising the isomerization of glucose into fructose.

  • Method for preparing dialkyloxydianhyrohexitol by etherification of dianhydrohexitol using a light alcohol, in the presence of an acidic catalyst
    Patent number: 9321783
    Abstract: 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.
