In excess, O2 similar processes produce primarily CO2 and H2O and these processes are very important to reduce pollution from NOx, CO, and unburned hydrocarbons in combustion to produce heat, radiation, and for the abatement of volatile organic compounds (VOCs) in air.

ScienceDirect ® is a registered trademark of Elsevier B.V. The ability of the complex to catalyze oxidation of several alkanes and alkenes has been investigated by using CH3COOH/H2O2 (1:1) as an oxidative system. Di- and Tetrairon(III) μ-Oxido Complexes of an N3S-Donor Ligand: Catalyst Precursors for Alkene Oxidations. It is shown that this oxidation reaction is not based on O2 activation by the nonheme iron catalysts as in Nature but due to a radical-based initiation, followed by a radical- and ferryl-based catalytic reaction. These results can be explained as occurring by purely surface reaction steps. Metal Complexes Containing Redox-Active Ligands in Oxidation of Hydrocarbons and Alcohols: A Review. Partial oxidation of methane-rich flames does produce syngas and steam cracking is a homogeneous process that produces olefins at comparable selectivities to those described in the chapter. is available on our Permission Requests page. Catalytic oxidation of alkanes at millisecond contact times. . Partial retention of configuration (RC = 53 %) in cis‐ and trans‐1,2‐dimethylcyclohexane oxidation, moderate 3°/2° selectivity (4.1) in adamantane oxidation, and the observation of a relatively high kinetic isotope effect for cyclohexane oxidation (KIE = 3.27) suggest partial metal‐based oxidation, probably in tandem with free‐radical oxidation. the whole article in a third party publication with the exception of reproduction 2010).

They identified a precursor-mediated mechanism and reported the energy barriers for the various alkane molecules. . This chapter discusses experiments where these processes are used to produce syngas by partial oxidation of methane, olefins by partial oxidation of higher alkanes, and combustion products by total oxidation of alkanes. Organic substrates (specifically cis-1,2-dimethylcyclohexane, DMCH) are oxidized by O2 in the presence of iron(II)–bispidine complexes.
