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.
A process for conversion of an aromatic feedstock to an oxidized aromatic product comprising at least one aromatic carboxylic acid comprising contacting an aromatic feedstock comprising a substituted aromatic hydrocarbon having at least one oxidizable substituent group with oxygen in a liquid reaction mixture comprising the aromatic feedstock, oxygen, water, not more than 10 wt. % C1-8 monocarboxylic acid, and a catalyst composition comprising palladium and at least one of antimony, bismuth and gold, wherein particles dispersed on a surface of the catalyst comprise at least a portion of the palladium in combination with at least a portion of at least one of antimony, bismuth or gold, to convert the aromatic feedstock to an oxidized aromatic product comprising at least one aromatic carboxylic acid.
