Patel, N. C. published the artcileSynthesis of bisazo disperse dyes based on 4-hydroxyl-1-phenylquinolin-2(1H)-one system and their dyeing performance on polyester fabric, Application In Synthesis of 14580-22-4, the publication is Journal of Indian Council of Chemists (2001), 18(1), 59-62, database is CAplus.
Ten 3-[4-(arylazo)phenylazo]-4-hydroxy-1-phenyl-2(1H)-quinolinone dyes were prepared by coupling diazotized 3-(4-aminophenylazo)-4-hydroxy-1-phenyl-2(1H)-quinolinone with various coupling components. 4-Hydroxy-1-phenyl-2(1H)-quinolinone (I) was prepared by the condensation of o-chlorobenzoic acid and aniline giving N-phenylanthranilic acid followed by acetylation giving N-acetyl-N-phenylanthranilic acid and ring closure. I was coupled with diazotized 4-aminoacetanilide giving a monoazo compound which on hydrolysis gave the diazo component for disazo dye preparation The dyes were characterized by elemental and spectral analyses and their dyeing performance on polyester fabric was assessed. The dyes when applied on polyester fabric gave shades with poor to good light fastness, very good to excellent wash fastness, and poor to excellent exhaustion.
