  • Patent number: 9260403
    Abstract: Provided are methods of producing 2,5-furandicarboxylic acid (FDCA) from renewable sources such as seaweed, alginate, oligoalginate, pectin, oligopectin, polygalacturonate, galacturonate, and/or oligogalacturonate. The sugars in the renewable sources can be converted into one or more intermediates such as 4-deoxy-L-erythro-5-hexoseulose uronate (DEHU), 4-deoxy-L-threo-5-hexosulose uronate (DTHU), 5-hydroxymethyl furfural (HMF), 2,5-dihydroxymethyl furan (DHMF), and 5-formyl-2-furancarboxylic acid (FFA), which can be converted into FDCA by dehydration and cyclization to produce 5-formyl-2-furancarboxylic acid (FFA), followed by oxidation to produce FDCA. DEHU or DTHU may also be converted into FDCA by oxidation to produce 2,3-dihydroxy-5-oxohexanedioic acid (DOHA), which then undergoes dehydration and cyclization to produce FDCA.

  • Patent number: 9221741
    Abstract: Ketocarboxylic acids such as levulinic acid can be efficiently purified in high yield by esterification with a hydrocarbon polyol to the corresponding polyketocarboxylic ester, which can be readily purified, for example recrystallized. After purification, the ketocarboxylic ester can be hydrolyzed to provide pure ketocarboxylic acid, or a salt thereof, after removal of the esterifying hydrocarbon polyol, or used for other synthetic transformations. Advantageously, the polyketocarboxylic esters, ketocarboxylic acids, and salts thereof produced by this method are obtained in high purity.

  • Patent number: 9018127
    Abstract: A reduced metallic catalyst or pre-activated catalyst is formed by contacting a precursor catalyst or a reduced metallic catalyst with a modifier solution in the presence of a source of hydrogen and heat treating the precursor catalyst or the reduced metallic catalyst at super-atmospheric pressure to obtain the reduced metallic catalyst from the precursor catalyst or the pre-activated catalyst from the reduced metallic catalyst. A method of hydrogenating a hydrogenatable precursor includes providing a reduced metallic catalyst or the pre-activated catalyst prepared with modifier buffer and contacting the reduced metallic catalyst or pre-activated catalyst with the hydrogenatable precursor in the presence of hydrogen and, optionally, in the presence of a modifier solution.

  • Patent number: 8895779
    Abstract: A process for making MAA from a clarified DAA-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes MAA, at least some DAA, and at least about 20 wt. % water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a DAA-containing liquid portion in contact with a MAA-containing solid portion that is substantially free of DAA; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
