Аннотация:The UV and IR spectra of products formed at various stages of the ozonization of phenol and guaiacol in distilled water and the kinetics of ozone reactions with phenol and guaiacol were studied. The oxidation of phenol with ozone involved successive stages of the formation of acids and aldehyde acids with two and one C=C bonds and the stage of the formation of glyoxalic acid. The rates of these reactions were commensurate. The oxidation of the guaiacol aromatic ring by ozone occurred at a much higher rate than the oxidation of phenol. The end products of the ozonolysis of phenol were formic and oxalic acids. With guaiacol, esters of these acids were also formed. The results of the spectral study of the ozonolysis of phenol and guaiacol were in agreement with the conclusions drawn based on kinetic data
