Cyanuric chloride is condensed with H acid, then condensed with p-phenylenediamine, and then diazotized with anthranilic acid, coupled with the condensate to synthesize Reactive Red 120.
Red sauce color powder. Solubility in water (50℃) is 90g/L. The aqueous solution is bright red, add 1mol/L sodium hydroxide solution to turn orange-red, then add insurance powder and warm to turn orange, and there is a slight precipitation, then add sodium perborate to turn light yellow. In concentrated sulfuric acid, it is purplish red, and after dilution, it turns peach color. Dark red in concentrated nitric acid, red after dilution.
Reactive Red 120 acts as an azo textile dye used in fabric and the paper industry.
2-Aminobenzenesulfonic acid diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acidcoupling, and 2,4,6-Trichloro-1,3,5-triazine first condensation, its product (2 Moore) and Benzene-1,4-diaminesecond condensation.
ChEBI: A bis(azo) compound that consists of a benzene core having two (4-amino-6-chloro-1,3,5-triazin-2-yl)amino groups attached at positions 1 and 4 and which in turn have 5-hydroxy-6-[(2-sulfophenyl)diazenyl]-2,7-disulfonaphthalen-4-yl groups attached to their
-amino functions.
Properties and Applications
colourful red blue light. Red uniform powder. Soluble in water, 50 ℃ in the water when the solubility of more than 140 g/L. Dyeing color for colourful blu-ray red, dyeing in light of iron ion slightly to yellow (category 4); Copper ions in turn light blue (level 2). Compatibility is high, the reaction of the medium, and easy to wash the gender is good. Mainly used for cotton or viscose fiber volume dye and disseminated, also can be used for direct printing, also suitable for polyester/cotton, polyester/stick blended dyeing.
