Direct Attack

The hydrolysis of the quaternary ammonium salts of methyl-bis-β-chloroethylamine is inhibited by both hydrogen ions and chloride ions. I he kinetics of hydrolysis in various anion solutions suggest that reaction occurs by direct attack at the β-chlorine atoms by hydroxyl ion.

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.
