Chemical Reactivity of Cyanogen Chloride in Aqueous Solution

Abstract

The hydrolysis of cyanogen chloride at several pH values has been studied and rate constants for acid and base catalysis are reported. The catalysis by phosphate ions has been investigated. We have continued our study of the reaction between cyanogen chloride and different nitrogen nucleophiles. Rate constants for the reaction of cyanogen chloride with glycine, glycinamide, and benzylamine are reported. In addition a very careful study over a wider range of pH for the reactions between cyanogen chloride and several amines has been carried out. Our earlier work was covered in reports no. 1 and 2. In view of the new results, it is evident that there is a significant acid catalysis of the hydrolysis reaction at low pH values where the concentration of free amine is very small. As a consequence the rate constant values reported earlier have been corrected considering the acid catalysis of the water and the protonated amine reactions. The interaction between cyanogen chloride and transition metal ions has been studied using nickel (II) chloride and ferrous chloride as sources of metal ions. Previous results on this matter are also included in this report.
