Abstract

A thermal analysis study has been performed for the stable free radical 2,2-diphenyl-1-picrylhydrazyl and other ten free radical congeners, together with their corresponding parent hydrazines. Qualitative studies on the decomposition products showed that nitrogen dioxide plays a key role. A mechanistic decomposition pathway is also proposed.
