The kinetics of the syntheses of N-alkyl, N,N-dialkyl, and N-(4-substituted phenyl) O-ethyl thioncarbamates from sodium ethyl xanthogenacetate, ten alkylamines, and eight substituted anilines were studied at 25, 30, 35, and 40 °C. The reactions were found to follow second-order kinetics. The kinetic (Arrhenius) parameters, such as the activation energy and the frequency factor, as well as the Eyring parameters, such as the standard entropy, the standard Gibbs energy, and the standard enthalpy of activation, were calculated from the second-order rate constants. The mechanism of the reaction was postulated based on the kinetic studies presented and the optimization of the reaction mechanism using the MOPAC PM6 semi-empirical method.

In a study on the ethanolysis of thioureas it is demonstrated that N,N'-di- and trisubstituted aryl- and alkylarylthioureas when heated in ethanolic solution undergo fission to give N-arylthiocarbamic acid O-ethyl esters and amines. The reaction rates are depending on the nature of the substituents on the phenyl rings. Generally, the reactions are promoted by mineral acid.

The second order-rate constants for the addition of water and ethanol to p-nitrophenyl isothiocyanate are larger in dimethyl sulphoxide solution than in pure water or ethanol.The detailed behaviour over a wide composition range suggests that H-bonding by
