| Hazard Information | Back Directory | [Chemical Properties]
Orange powder. Solubility in water (50°C) is 100g/L. The aqueous solution is golden yellow. Addition of 1 mol/L sodium hydroxide solution turns dark yellow. Addition of hydrosulfite does not change the color even when warm, nor does addition of sodium perborate. In concentrated sulfuric acid, it turns reddish brown, but golden yellow upon dilution. In concentrated nitric acid, it turns golden yellow, but remains unchanged upon dilution. Resistant to alkaline hydrolysis, but not acidic hydrolysis. | [Uses]
Reactive Orange 1 is mainly used for dyeing cotton, linen, viscose, and other fiber yarns and fabrics. It is generally not used for printing because it has high affinity and is prone to color differences. It can also be used to dye wool, silk, and nylon. For example, it can be used to dye bright red silk and spun silk in combination with Brilliant Red XB, and to dye maroon viscose and silk interwoven pile in combination with Red-Purple X-2R. It is also used for direct printing on silk and two-bath dyeing of polyester/cotton blended fabrics. | [Preparation]
2-Aminobenzenesulfonic acid diazo, and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, and then again with 2,4,6-Trichloro-1,3,5-triazine?condensation. | [Properties and Applications]
bright orange. Yellow light red powder. Solubility 100 g/L (50 ℃). In the 20 to 40 ℃ can in alkaline medium of the fibers in dyeing, levelness is better. Alkaline hydrolysis, not resistant to acid hydrolysis. The strong sulfuric acid for red, diluted into red orange; In nitric acid to orange, no change after diluted. Water solution is orange, add 1 Moore sodium hydroxide to a bit deep red, continue to add insurance powder and warm, into light yellow, join a boric acid sodium can’t return to them. Apply to cotton, wool, silk, nylon and viscose fiber yarn and fabric dyeing, suitable for dyeing or disseminated, high affinity. Viscose fabric can also be used for direct, resist printing..
