Permanganate oxidation of benzaldehyde and p-nitrobenzaldehyde goes by two paths, i.e. a major one which is responsible for the normal oxidation giving good second order kinetic and minor path which involves a very small percent of a radical species formed by hydrogen atom abstraction by the permanganate ion. A mechanism involving Hydrogen atom abstraction by permanganate from the alkoxide ion ...

Photo-oxidation products from the reaction of a series of alkyl-benzenes, (benzene, toluene, p-xylene and 1,3,5-trimethyl-benzene) with hydroxyl radicals in the presence of NOx have been investigated using comprehensive gas chromatography (GCXGC). A GCXGC system has been developed which utilises valve modulation and independent 5 separations as a function of both volatility and polarity. A numb...

Catalytic oxidation is regarded as an effective, economical, and practical approach to remove volatile organic compounds such important air pollutants. CeO2 catalysts with different morphologies exhibit oxygen vacancies content, which plays a vital role in reaction. Herein, three distinct of i.e., shuttle (CeO2 (S)), nanorod (R)), nanoparticle (P)), were successfully fabricated by the SEM TEM r...

We report the photocatalytic oxidation of benzylic carbon atoms under mild conditions using riboflavin tetraacetate as photocatalyst and blue-emitting LEDs (440 nm) as light source. Oxygen is the terminal oxidant and hydrogen peroxide appears as the only byproduct in most cases. The process oxidizes toluene derivatives, stilbenes, styrenes and phenylacetic acids to their corresponding benzaldeh...
