purpose	weak acid orange C- GNS is mainly used for nylon dyeing. Can be used alone, can also be combined with red, blue acid dyes orange, beige, olive and gray color. High dyeing rate, good levelness, excellent light fastness. for dyeing and printing of nylon, silk and wool fabrics
production method	using p-aminobenzenesulfonic acid, 3-amino-4-methoxytoluene and phenol as raw materials, the p-aminobenzenesulfonic acid was first diazotized, it is coupled with 3-amino-4-methoxytoluene, and then the coupled product is subjected to a second diazotization, and then coupled with phenol, and finally the phenol hydroxyl group is methylated to obtain the product. The final product was obtained by filtration, drying and pulverization..
