Synthesis and Dyeing Performance of Monoazo Reactive Dyes Based on 4-Oxoquinazoline

A series of different types monoazo reactive dyes were synthesied, where various amino adds was diazotosed and coupled with styryt Outnazoline, which was produced on condensation with cyanuretad a*naphthoi. These monoazo reactive dyes produces orange to pink shades on cotton, wool and stk the purity of afl dyes have bean checked by thin layer chromatography. The IR spectra of all these dyes showed afl characteristic band present in the dye molecules. This dyes whan apfHart on cotton, woof and s»k fabric in 2% shade show fair to good fastness to light, wasting and nibbing.
