  • Publication number: 20080091043
    Abstract: The present invention relates to a process for producing an organic acid or its derivatives, which comprises oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst and an oxidant. In particular, the present invention relates to a process comprising oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst selected from Co/Br, Mn/Br, Co/Mn/Br and Co/Mn/M/Br and an O2/CO2 mixed gas oxidant where the partial pressure of O2 is controlled to 30-40%, thereby improving the oxidation rate, the conversion, the selectivity and the yield even under milder conditions. Especially, the present invention remarkably reduces down to a negligible level the production of color impurities and other impurities such as 4-CBA and p-toluic acid, which had been conventionally removed by hydrogenation reduction. Further, the loss in acetic acid solvent due to combustion can also be drastically decreased using the method of the present invention.

  • Patent number: 6048451
    Abstract: A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. Suitable alkylating agents include alcohols and olefins. In a preferred embodiment, catalytic cracking products which contain aromatic sulfur compounds as impurities are used as a feedstock for the process.

  • Patent number: 5324702
    Abstract: Compositions comprising certain metal-containing materials distributed interactively on a deboronated HAMS-1B crystalline borosilicate molecular sieve which are useful for catalytically oxidizing or oxidatively dehydrogenating organic compounds such as alkanes, aromatics, and alkyl-substituted aromatics are described. Alkanes are oxidatively dehydrogenated to olefins, and an aromatic compound such as benzene can be oxidized by nitric and/or nitrous oxide to largely phenol or largely nitrobenzene depending upon the oxidation temperature. When the compound is a methylaromatic, oxidation produces an aromatic aldehyde. Alkyl groups larger than methyl oxidatively dehydrogenate to alkenyl groups.
