SYNTHESIS AND APPLICATIONS OF SOME REACTIVE DYES HAVING QUINAZOLIN-4(3H)-ONE MOIETY

Some reactive dyes (6a-6l) having Quinazolin-4(3H)-one system have been synthesized by coupling of diazotized 3-(4-(5-(4-aminophenyl)-1,3,4-oxadiazol-2-yl) phenyl)-4-oxo-2-phenyl-3,4-dihydroquinazoline-6-sulphonic acid with cyanurated components such as H-acid, J-acid, N-methyl Gamma acid, Peri Sulpho Tobias Koch Bronners Chicago K-acid, N-Phenyl J-acid and M-acid. The were characterized nitrogen elemental analysis, IR, 1H-NMR spectra. They applied on wool, silk, cotton fibres. Their dyeing properties, fastness colorimetric data (L*, a*, b*, C*, H*, K/S) also investigated.
