Selective Oxidation of Hydrocarbons on Composite Oxides

Catalysis Reviews, 1979
Abstract A catalyst for the selective oxidation of hydrocarbons to unsaturated aldehydes, acids, acid anhydrides, divinyls, or styrenes has to perform several functions. First, it must supply a limited amount of oxygen to the reactant, sufficient to allow the formation of the desired product but not enough to allow complete oxidation.

5-Methylcytosine-Selective Osmium Oxidation

Nucleosides, Nucleotides and Nucleic Acids, 2007
Methylcytosine was efficiently and easily modified through osmium oxidation. Methylcytosine-selective oxidation is applicable to detection of the cytosine methylation status at a specific site of a long sequence using the formation of a bulge structure by hybridization with a guide DNA.

Tungsten oxides as catalysts in selective oxidation

Journal of Catalysis, 1983
Abstract The reaction of allyl iodide was studied at the surface of four tungsten oxides and molybdenum trioxide. On WO2.95 and MoO3, in which crystallographic shear structures are formed on reduction, acrolein is produced at 300–400 °C, whereas W18O49 and WO2, which do not show this property, are inactive, as is WO3.

Selective Oxidation of Propylene

1979
Publisher Summary This chapter focuses on a single aspect of selective hydrocarbon oxidation, the selective oxidation of propylene to acrolein, with the questions in mind, such as “How is propylene activated? What is the nature of the reactive oxygen species?” The selective oxidation of propylene is an important model reaction for studying oxidation ...

Selective Oxidation/Dehydrogenation Reactions

2013
Gold catalysts were extensively studied in the selective oxidation of ethanol into acetic acid and ethyl acetate. Gold supported on titania was found to be the most promising catalysts, demonstrating the low temperature (120oC) catalytic activity even in the gas phase. Reaction kinetics and structure sensitivity were investigated.
