Abstract
Organic compounds of the different classes of substances (isobarbituric acid, citraconic acid and o-chlorophenol) were ozonized while varying their initial concentrations (c = 10-3 to 10-5 mol/L) at pH 7. In the case of isobarbituric acid at 10-3 mol/L, formyloxaluric acid, oxaluric acid, and formic acid were identified. At an initial concentration of 10-3 mol/L, alloxanic acid and oxalic acid were formed in addition to oxaluric acid and formic acid. In both cases, the rates of elimination are similar.After ozonation of citraconic acid (c = 10-5 mol/L, pH 7), the following oxidation products were identified: glyoxylic, acetic, formic, oxalic, pyruvic, and hydroxypyruvic acids.
