Application	disperse Yellow 5G is suitable for dyeing and printing polyester and its blended fabrics, and also used for dyeing acetate fiber, triacetate fiber, the coloring of nylon, nylon and plastics. It is mainly used for dyeing polyester and its blended fabrics, and also used for dyeing acetate and nylon
production method	with M-nitroaniline, O-aminobenzoic acid and phthalic anhydride as raw materials, O-aminobenzoic acid was first methylated with dimethyl sulfate, ring closure is then performed with phthalic anhydride to give 1-methyl-4-hydroxy-2-quinolone (I). The product is then obtained by diazotization of M-nitroaniline and coupling with (I). The final product was obtained by filtration and drying..
