Abstract: Arylthioureas, which are toxic, on oxidation by cetyltrimethylammonium dichromate in acetic acid undergo desulphurization to the corresponding non-toxic arylureas. The mechanism of the oxidation reaction has been studied spectrophotometrically. The rate of reaction is found to be dependent on [CTADC], [phenylthiourea], [acid], [surfactant], polarity of the solvents and reaction temperature. The reaction is fractional order with respect to [substrate] and is catalyzed by acid. With increase in [CTADC], the rate constant decreases. The structure of the substituents has no significant effect on the rate constant. On the basis of various observations, a mechanism has been proposed for the oxidation reaction.
