New reactive-disperse dyes

Four new reactive-disperse, 4 new disperse and 2 new reactive dyes were synthesised. The molecule of the reactive-disperse dye contains as a reactive hook an epoxide ring in which a 4-nitrophenyl group substituted at one of its carbon atoms, meanwhile is considered as a derivative of 2,4-dinitrodiphenyl-amine thus acquiring the properties of disperse dyes. The present reactive-disperse dyes are useful for dyeing polyester-cotton blends

Mixed ligand complexes of copper [II] -4-nitrobenzeneazoresorcinol complex with unidentate ligands

The formation constants of mixed ligand complexes of copper [II]-4-Nitrobenzeneazoresorcinol complex with unidentate ligands were determined by spectrophometric method at 25°C. The data of the inner sphere complex are related with both the electron donor and basicity constants of the unidentate ligands
