Molecular Formula	C40H23Cl2N15Na6O19S6
Molar Mass	1418.93434
Appearance	Powder
Color	Dark blue
Physical and Chemical Properties	Reactive dark green KE-4BD is a black (or dark green) powder. The solubility in water (50 °c) is 65g/L. The aqueous solution was dark blue-green in color, and 1mol/L sodium hydroxide solution was added to turn blue, followed by addition of sodium hydrosulfite and warming to colorless, followed by addition of sodium perborate to remain colorless. In concentrated sulfuric acid was dark green, diluted dark crab cyan. It was purple in concentrated nitric acid and turned black-brown after dilution.

Simactive Green 25023 - Reference Information

introduction	active dark green KE-4BD is also called active green 19. There are many reports that there are a variety of strains can be degraded, such as double enzyme Clostridium, Shiwanella and Leria verrucosa.
use	reactive green KE-4B is suitable for dyeing cotton and viscose fibers. dip dyeing, roll dyeing and pad dyeing can be used, with high dye uptake and fixation rates. It is also used for direct weaving of cotton and viscose fiber fabrics, and the fixation rate can reach more than 90%. It is also used for dyeing hemp, polyester cotton and polyester viscose fabrics. for dyeing and printing of cotton fibers for dyeing of cotton and hemp fabrics
production method	active dark green KE-4BD can be made of h acid, p-nitroaniline o-sulfonic acid, cyanuric chloride and p-aminobenzenesulfonic acid as raw materials. first, p-nitroaniline o-sulfonic acid is diazotized, coupled with h acid, reduced by sodium sulfide, condensed with cyanuric chloride for the first time, and then condensed with p-aminobenzenesulfonic acid for the second time to obtain the product. The finished product is salted out, filtered and dried.
