The potassium permanganate oxidation of methylated humic acid from a Spanish lignite yielded mainly straight-chain alkanes together with a mixture of fatty acids, methyl straight-chain alkyl ketones, aliphatic dicarboxylic, phenolic and benzenecarboxylic acids. Furthermore, some unusual compounds such as dehydroabietic and bromohydroxybenzoic acids and bis(2-ethylhexyl)phthalate were also ident...

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

The most troublesome obstacle to the quantitative determination of the very minute quantities of iodine which are normally present in biological materials has been the destruction, without loss of iodine, of the relatively large amounts of organic matter present. The procedures which have been used to destroy the organic matter include fusion with alkali, combustion in a closed system, and dige...

The title compound, C(22)H(22)N(2), was prepared by the reaction of 4-amino-toluene with sodium carbonate, sodium hydroxide and potassium permanganate. The mol-ecule is disposed about a crystallographic inversion centre with one half-mol-ecule comprising the asymmetric unit. The dihedral angle between the terminal and central benzene rings is 88.05 (1)°. The crystal packing is stabilized by van...

Potassium permanganate (KMnO4) and oleic acid (OA) were purchased from Alfa Aesar. Glutathione (GSH), 3-(4,5-dimethylthialzol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), alpha lipoic acid (ALA), buthionine sulfoximine (BS) and N-ethylmaleimide (NEM) were purchased from Sigma-Aldrich. Doxorubicin hydrochloride (DOX) was purchased from Dingguo reagent company (Beijing, China). All buffers were p...
