Trinitrotoluene as a precursor in synthesis of effective azodyes and azopygments

Abstract

The results of investigations of chemical transformations of trinitrotoluene and trinitrobenzene into azodyes and azopygments are presented. About 90 new ammino- and azocompounds were synthezised and investigated by a set of spectroscopic and theoretical methods and tested as acid and disperse dyes with high resistance to physical and chemical treatments
