  • Patent number: 10017486
    Abstract: The present invention relates generally to processes for converting fructose-containing feedstocks to a product comprising 5-(hydroxymethyl)furfural (HMF) and water in the presence of water, solvent and an acid catalyst. In some embodiments, the conversion of fructose to HMF is controlled at a partial conversion endpoint characterized by a yield of HMF from fructose that does not exceed about 80 mol %. In these and other embodiments, the processes provide separation techniques for separating and recovering the product, unconverted fructose, solvent and acid catalyst to enable the effective recovery and reutilization of reaction components.

  • Patent number: 9783473
    Abstract: Processes are disclosed for the conversion of a carbohydrate source to hexamethylenediamine (HMDA) and to intermediates useful for the production of hexamethylenediamine and other industrial chemicals. HMDA is produced by direct reduction of a furfural substrate to 1,6-hexanediol in the presence of hydrogen and a heterogeneous reduction catalyst comprising Pt or by indirect reduction of a furfural substrate to 1,6-hexanediol wherein 1,2,6-hexanetriol is produced by reduction of the furfural substrate in the presence of hydrogen and a catalyst comprising Pt and 1,2,6-hexanediol is then converted by hydrogenation in the presence of a catalyst comprising Pt to 1,6 hexanediol, each process then proceeding to the production of HMDA by known routes, such as amination of the 1,6 hexanediol. Catalysts useful for the direct and indirect production of 1,6-hexanediol are also disclosed.
