Catalytic Oxidation of 4-Methylpyridine on Modified Vanadium Oxide Catalysts
The reaction of gas-phase oxidation of 4-methylpyridine on individual V2O5, binary and ternary vanadium-oxide catalysts was studied. These catalysts were modified by additives of SnO2 and TiO2. It was found that modifying V2O5 leads to increase the activity of binary contacts. Upon transition from binary V2O5<...
متن کاملChemical Oxidation of Cyclophosphamide and 4-Methylcyclophosphamide1
has been studied and the formation of acrolein as a product confirmed by gas chromatography-mass spectrometry. Oxi dation of 4-methylcyclophosphamide generates methyl vinyl ketone. This is interpreted to indicate that the acrolein and methyl vinyl ketone arise from oxidation of position 4 of the ring of cyclophosphamide. The Fenton oxidation of both cyclophosphamide and 4-methylcylophosphamide ...
متن کاملAssociation of Interleukin-4 and IgE Levels with LDL Oxidation in Atherosclerosis
Background: Atherosclerosis is an inflammatory and multifactorial disease, with a high prevalence rate in Pakistan. Objective: To find a relation between serum IL-4 and IgE levels with oxidized LDL in atherosclerosis. Methods: In this observational, cross sectional study 99 male patients, between forty and sixty years of age, with a history of ischemic heart disease (IHD) and established athero...
متن کاملOxidation of substituted 4-fluorobenzaldehydes: application to the no-carrier-added syntheses of 4-[18F]fluoroguaiacol and 4-[18F]fluorocatechol.
The synthesis of 4-[18F]fluoroguaiacol (4-[18F]fluoro-2-methoxyphenol) has been achieved in no-carrier-added form starting from 2-methoxy-4-nitrobenzaldehyde, using nucleophilic aromatic substitution by [18F]fluoride followed by Baeyer-Villiger oxidation of the benzaldehyde to the phenol. Demethylation with boron tribromide gave 4-[18F]fluorocatechol (1,2-dihydroxy-4-[18F]fluorobenzene) with an...
متن کاملStereochemical aspects of the oxidation of 4-ethylphenol by the bacterial enzyme 4-ethylphenol methylenehydroxylase.
The O2-independent hydroxylase 4-ethylphenol methylenehydroxylase (4EPMH) from Pseudomonas putida JD1 catalysed the complete conversion of 4-ethylphenol into 1-(4-hydroxyphenyl)ethanol together with a small amount of 4-hydroxyacetophenone, but with no formation of the side product 4-vinylphenol reported to be formed when the similar enzyme p-cresol methylhydroxylase (PCMH) catalyses this reacti...
