  • Patent number: 9206147
    Abstract: The present invention relates to a method for producing a furan-based compound using an ion exchange resin in the presence of an organic solvent. In the method for producing a furan-based compound according to the present invention, a furan-based compound is made from an aldose-type hexose compound in the presence of an organic solvent by using an anion exchange resin and a cation exchange resin. Thus, the aldose-type hexose compound obtained from biomass by simultaneously or consecutively using the anion/cation exchange resins as catalysts can be made into 5-hydroxymethyl-2-furfural (HMF) or alkyl ether derivatives thereof such as 5-alkoxymethyl-2-furfural (AMF) without using an expensive reagent. Also, since the selection of an organic solvent is not limitative and a heterogeneous catalyst can be used, separation and purification is easy and chemically stable AMF can be directly obtained.

  • Patent number: 9199923
    Abstract: In recognition of the need to develop novel therapeutic agents, the present invention provides novel histone deacetylase inhibitors. These compounds include an ester bond making them sensitive to deactivation by esterases. Therefore, these compounds are particularly useful in the treatment of skin disorders. When the compounds reaches the bloodstream, an esterase or an enzyme with esterase activity cleaves the compound into biologically inactive fragments or fragments with greatly reduced activity Ideally these degradation products exhibit a short serum and/or systemic half-life and are eliminated rapidly. These compounds and pharmaceutical compositions thereof are particularly useful in treating cutaneous T-cell lymphoma, neurofibromatosis, psoriasis, hair loss, skin pigmentation, and dermatitis, for example. The present invention also provides methods for preparing compounds of the invention and intermediates thereto.

  • Patent number: 9181209
    Abstract: Furfural is produced by mixing an aqueous feedstock solution containing C5 sugar and/or C6 sugar with a heated, high boiling, water-miscible solvent, such as sulfolane, and a soluble acid catalyst. Furfural product and water are distilled off through a multistage distillation column, leaving non-volatile solvent behind. Typical furfural yields with sulfolane as the reaction solvent are about 80% at as high as 99% conversion. Also, certain by-products (e.g., humins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous feedstock solution and then removed by filtration, thereby providing a convenient and effective way of removing these undesirable byproducts from the reaction mixture.

  • Patent number: 9181211
    Abstract: Furfural is produced by mixing an aqueous feedstock solution containing C5 sugar and/or C6 sugar with a heated high boiling, water-miscible solvent, such as sulfolane, and a solid acid catalyst. Furfural product and water can be distilled off, leaving non-volatile solvent behind. Furfural yields of over 70% at as high as 99% conversion have been obtained with this process with sulfolane as the reaction solvent and zeolite beta as the solid acid catalyst. Also, certain by-products (e.g., humins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous feedstock solution and then removed by filtration, thereby providing a convenient and effective way of removing these undesirable byproducts from the reaction mixture.
