A micro-scale quantitative method for low-molecular-weight monocarboxylic (C,-C,) and dicarboxylic (C&C,) acids in permanganate oxidation products of humic substances (kerogen) was established. The oxidation products were butylated by n-butanol in the presence of concentrated sulphuric acid in a sma

The reaction of permanganate ion with pyruvic acid and lactic acid has been studied in aqueous solutions containing 0.10-2.0 mol dm-3 alkali. In this range of HOconcentration the reaction 2Mn04 -+ Substrate -2Mn04 \*-+ product is followed slowly by the reduction of manganate, thus, the above process
The oxidation mechanism of aldehydes with permanganate was studied in acidic and alkaline media on acetaldehyde, propionaldehyde, pivalaldehyde (2,2ะ-dimethylpropanal) and chloral substrates. On addition of water to acetaldehyde dissolved in organic solvents the rate increased, and therefore it may
The kinetics of the oxidation of mandelic acid (MA) by permanganate in aqueous alkaline medium at a constant ionic strength of 1.0 mol dm ร3 were studied spectrophotometrically. The reaction shows first-order kinetics in [permanganate ion] and fractional order dependences in [MA] and [alkali]. Addit
## Abstract A study was made on permanganate oxidation of olefinic and acetylenic alcohols in aqueous alkali media. Deprotonation constants of alcohols can be calculated from the kinetic data. The rate constant of alkoxide group oxidation exceeded that of the unsaturated bond. For oxidation of the
