Abstract
Four derivatives of 3-hydroxy1-phenyl-3-alkyltriazene have been synthesized and their hydrolytic stability has been measured in sulphuric acid medium (0.2-16 mol l-1). The rate constant has been found to increase with increasing concentration of sulphuric acid at first, but, on the contrary, at higher concentrations it decreases. Twelve kinetic schemes of acid catalysis have been suggested and evaluated, and a probable mechanism of decomposition has been suggested which involves nitrenium ion as an intermediate.
