Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Furan-2,5-dicarboxylic acid purge process

A process for purifying a crude furan 2,5-dicarboxylic acid composition (cFDCA) by hydrogenation of a FDCA composition dissolved in a hydrogenation solvent such as water, and hydrogenating under mild conditions, such as at a temperature within a range of 130&#xb0; C. to 225&#xb0; C. by contacting the solvated FDCA composition with hydrogen in the presence of a hydrogenation catalyst under a hydrogen partial pressure within a range of 10 psi to 900 psi.

Purifying crude furan 2,5-dicarboxylic acid by hydrogenation and a purge zone

A process for purifying a crude furan 2,5-dicarboxylic acid composition (cFDCA) by hydrogenation of a FDCA composition dissolved in a hydrogenation solvent such as water, and hydrogenating under mild conditions, such as at a temperature within a range of 130&#xb0; C. to 225&#xb0; C. by contacting the solvated FDCA composition with hydrogen in the presence of a hydrogenation catalyst under a hydrogen partial pressure within a range of 10 psi to 900 psi. A product FDCA composition is produced having a low amount of tetrahydrofuran dicarboxylic acid, a low b*, and a low amount of 5-formyl furan-2-carboxylic acid (FFCA).

Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

Disclosed is a halide-free catalyst system and method for oxidizing toluene to form benzoic acid in benzoic acid solvent. The catalyst system contains Co, at least one of Zr and Hf, and an alkali metal basic salt.

Purifying crude furan 2,5-dicarboxylic acid by hydrogenation

Oxidation process to produce a crude and/or purified carboxylic acid product

Catalyst compositions of alumina supports containing palladium and nickel are selective in a vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products.

Methods and apparatus for producing a carboxylic acid employing a solvent from esterification of lignocellulosic materials. An acid-containing composition from esterification of lignocellulosic materials can be employed in the oxidation of para-xylene to terephthalic acid. The acid-containing composition can comprise acetic acid, acetic anhydride, and one or more terpenes or terpenes derivatives.
