Acid yellow 127 (C.I. 18888) - Reference Information
| Use | neutral brilliant yellow 3GL is mainly used for dyeing hair and wool fabrics, mostly used for color matching, and also used for dyeing silk and nylon. In wool, silk, nylon fabric directly printed bright yellow, and suitable for discharge printing with color. Can also be used for leather coloring. |
| production method | with 2, 4-diaminobenzenesulfonic acid, cyanuric chloride, N-methylaniline, 1-(o-chlorophenyl)-3-methyl-5-pyrazolone as raw material, cyanuric chloride first with 2, 4-diaminobenzenesulfonic acid condensation, and then with N-methylaniline for the second condensation, and then the condensation product diazotization, the product is obtained by coupling with 1-(o-chlorophenyl)-3-methyl-5-pyrazolone. The final product was obtained by filtration and drying.. |
