A process including: (a) contacting an aqueous solution including a crude aromatic carboxylic acid with an oxygen source in the presence of an oxidation catalyst including at least one of Ru, Au, Pt, Ir or V, and oxides, alloys, salts and mixtures thereof; and (b) purifying the product of step (a) to form a purified aromatic carboxylic acid.

Oxidation process for preparing purified aromatic carboxylic acids

Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise solid particles comprising palladium in combination with at least one of antimony, bismuth and gold, and optionally, an additional metal or metalloid component effective to promote activity or selectivity of the palladium and antimony, bismuth or gold for oxidation to aromatic carboxylic acids. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such catalytic compositions in a liquid reaction mixture.

Process and catalyst for oxidizing aromatic compounds

Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise a combination comprising a palladium component, an antimony component and/or a bismuth component, and one or more Group 4, 5, 6 or 14 metal or metalloid components. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture.
