C.I. Reactive Yellow 18 Use and Manufacturing
Take aniline-2, 5-disulfonic acid, 2, 4-diaminobenzenesulfonic acid, cyanuric chloride, 1-(4'-sulfophenyl)-3-methyl-5-pyrazolone as Raw material, firstly, cyanuric chloride is condensed with aniline-2, 5-disulfonic acid, then with 2, 4-diaminobenzenesulfonic acid, and then another amino group in the 2, 4-diaminobenzenesulfonic acid molecule is heavy Nitriding, then coupling with 1-(4'-sulfophenyl)-3-methyl-5-pyrazolone, salting out, filtering and drying to obtain the finished product.
Used for printing cotton, linen, viscose, silk and other fabrics
