The present disclosure provides processes for the production of 2-5-furandicarboxylic acid (FDCA) and intermediates thereof by the chemocatalytic conversion of a furanic oxidation substrate. The present disclosure further provides processes for preparing derivatives of FDCA and FDCA-based polymers. In addition, the present disclosure provides crystalline preparations of FDCA, as well as processes for making the same.

Processes for the preparation of 2,5-furandicarboxylic acid and intermediates and derivatives thereof

The present disclosure provides processes for the purification of 2,5-furandicarboxylic acid (FDCA). The present disclosure further provides crystalline preparations of purified FDCA, as well as processes for making the same. In addition, the present disclosure provides mixtures used in processes for the purification of FDCA.

Purified 2,5-furandicarboxylic acid pathway products

Processes for separating a di-carboxylic acid or salt thereof from a mixture containing the di-carboxylic acid or salt thereof and one or more other components are provided. Also separation media useful for these separation processes is provided. In particular, processes for preparing an aldaric acid are described, such as glucaric acid from glucose, which includes separating the aldaric acid from the reaction product. Also, various glucaric acid products are described.

Preparation and separation of a di-carboxylic acid-containing mixture

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.

Conversion of fructose-containing feedstocks to HMF-containing product

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.

Process for production of hexamethylenediamine from carbohydrate-containing materials and intermediates therefor

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 proceding 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.

The present invention generally relates to processes for the chemocatalytic conversion of a glucose source to an adipic acid product. The present invention includes processes for the conversion of glucose to an adipic acid product via glucaric acid or derivatives thereof. The present invention also includes processes comprising catalytic oxidation of glucose to glucaric acid or derivative thereof and processes comprising the catalytic hydrodeoxygenation of glucaric acid or derivatives thereof to an adipic acid product. The present invention also includes products produced from adipic acid product and processes for the production thereof from such adipic acid product.
