Physical and Chemical PropertiesOrange powder. The solubility in water (50 °c) was 70g/L. The aqueous solution was golden yellow, and 1mol/L sodium hydroxide was added to turn dark yellow, followed by addition of sodium hydrosulfite and warming to light yellow, followed by addition of sodium perborate to remain light yellow. In concentrated sulfuric acid in a dark red color, and precipitation, diluted golden yellow. In concentrated nitric acid was golden yellow, diluted light yellow.

Application reactive brilliant orange K-GN is used for dyeing cotton or viscose fiber with low affinity and fixation rate, and is mainly used for direct printing, the white cloth staining less, not fixed dye easy to wash better. It is also used for silk fabric, silk and viscose fiber blended fabric, Vinylon printing and dyeing, two bath dyeing of polyester/cotton blended fabric. It can be combined with reactive yellow K-4G, reactive brilliant red K-2G, reactive brilliant red K-2BP and reactive brilliant blue K-GR to dye medium and deep colors.
used for dyeing and printing of cotton, hemp, viscose and other fabrics
production method aniline -2, 5-disulfonic acid, J acid, cyanuric chloride and M-aminobenzene sulfonic acid as raw materials, first, the J acid is condensed with cyanuric chloride, then the aniline -2, 5-bissulfonic acid is diazotized and coupled with the above condensation product, and finally the product is obtained by a second condensation with M-aminobenzenesulfonic acid. After salting out, filtration, drying to get the finished product... Condensation of 0.2625kmol of cyanuric chloride with 0.25kmol of J acid in hydrochloric acid medium at a temperature of 0-5 °c gives (I). After diazotization with 0.25kmol of aniline -2, 5-bissulfonic acid and coupling with (I), insoluble impurities were removed to obtain (II). After condensation with 0.275kmol of M-aminobenzenesulfonic acid at 40 ℃ for 3H, salting out, filtration, drying to obtain the finished product. See active Orange X-GN for the latest research results.
