The kinetics of hydrolysis of chlorine in acidic aqueous solutions was studied by the voltammetric method using a rotating gold disc electrode. The voltammetric curves consist of two waves, of which the more negative corresponds to reduction of hypochlorous acid and the more positive to reduction of chlorine. The wave of chlorine increases with the concentration of H+ and Cl- ions and has a kinetic character; in acetate buffer (pH 3.6) its behaviour approaches best the theory of kinetic-controlled waves. The corresponding dependences on the concentrations of H+ and Cl- ions, however, show some anomalies suggesting complications in the reaction mechanism.

The rate of hydrolysis of S2O82- ions in acidic medium to peroxomonosulphuric acid was measured at 20 and 30 °C. The composition of the starting solution corresponded to the anolyte flowing out from an electrolyser for production of this acid or its ammonium salt at various degrees of conversion and starting molar ratios of sulphuric acid to ammonium sulphate. The measured data served to calculate the rate constants at both temperatures on the basis of the earlier proposed mechanism of the hydrolysis, and their dependence on the ionic strength was studied.

Abstract The substance BK 129 - 1-[2-(2-pentyloxyphenylcarbamoyloxy)-(2-methoxymethyl)-ethyl]-perhydroazepinium chloride was prepared in terms of influence of the connecting chain between the carbamate functional group and the basic part of molecule on biological activity. Such a structural feature is important with regard to its stability. In this work we determined the rate constants of alkaline hydrolysis of this compound at increased temperature under isothermal and non-isothermal conditions. The hydrolysis was also performed in buffer solutions with the purpose of evaluating its stability. Non-isothermal tests of stability enable to reduce the number of analyses. The necessary data for stability of compound are in this way achieved in a short time.
