Benzenesulfonic acid, 2,5-dichloro-4-[4-[2-[2-[(ethylphenylamino)sulfonyl]phenyl]diazenyl]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]-, sodium salt (1:1) Use and Manufacturing
Using 2-amino-N-ethylbenzenesulfonanilide and 1-(2', 5'-dichloro-4'-sulfonic acid phenyl)-3-methyl-5-pyrazolone as raw materials, First, the former is diazotized, and then coupled with the latter to obtain the product. After filtering, drying and crushing, the finished product is obtained.
Weak acid yellow PL is used for the dyeing of wool, silk, nylon and its blended fabrics. It is also used for the direct printing of wool and silk fabrics and the ground color discharge printing of silk fabrics. It has good level dyeing. When the wool and other fibers are dyed in the same bath, the wool and nylon are dyed, the silk is stained seriously, the polyester and acrylic are stained, and the cellulose fiber and acetate fiber are not stained. It can also be used for leather coloring.
