  • Patent number: 8624055
    Abstract: 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.
    Type: Grant

  • Patent number: 8163954
    Abstract: 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.

  • Publication number: 20090118536
    Abstract: A process is disclosed for producing at least one aromatic carboxylic acid by contacting a liquid reaction mixture comprising an aromatic feedstock and water with oxygen in the presence of a bromine-free metal catalyst composition wherein the metal catalyst composition has activity in the absence of bromine for oxidation of the aromatic feedstock with at least 80% conversion to oxidized aromatic derivatives of the aromatic feedstock and with at least 80% selectivity to the aromatic carboxylic acid. This process operates in water without the use of bromine at temperatures and residence times substantially the same as conventional processes for aromatic carboxylic acid manufacture, as well as with less total burning and with yields to product equivalent or higher than conventional processes.

  • Publication number: 20090069594
    Abstract: Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise at least two metal or metalloid elements, at least one of which is palladium, platinum, vanadium or titanium, and at least one of which is a Group 5, 6, 14 or 15 metal or metalloid. 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.
