Appearance is flash brown red crystal or sand, melting point 118~118.5 °C. Soluble in water is yellow orange, soluble in ethanol and ethylene glycol ether, slightly soluble in acetone, insoluble in benzene. It is yellow in concentrated sulfuric acid and orange after dilution; it is orange solution in nitric acid. The aqueous solution was added to the sodium hydroxide solution to have a brown-red precipitate. The cotton fiber dyed in tannin mordant has a yellow-orange color and is more vivid under the tungsten light.

Basic Orange 2 Application:

Used for silk, wool, acrylic, tannin mordant dyeing cotton dyeing and printing, direct discharge printing. In addition, also used in leather, paper, feathers, plants and bamboo products dyeing.

Basic Orange 2 Use condition:

1.Silk dyeing: Basic orange 2(Chrysoidine) suitable for silk dyeing, carried out in an acetic acid bath. In the past, when silk was dyed black with hematoxylin, the color was adjusted. Now, printing on silk and other fabrics has rarely been applied.

2. Acrylic dyeing: There is a small amount of application in acrylic dyeing. In the acetic acid and sodium acetate bath, the dye bath pH is 4~5.5, and urea and retarder are added. Light fastness level 2, perspiration fastness 4~5, soaping fastness 4, dry rubbing fastness 4, wet rubbing fastness 3~4, ironing fastness 4~5, dry cleaning fastness level 4.

3. Wool dyeing: used for wool dyeing, in neutral or acetic acid bath, but the dyeing fastness is very poor, the light fastness is 1~2, and the soaping fastness is 1~2.

4. Cotton dyeing: cotton fiber can be dyed with tannin, and the cotton fiber dyed on tannin mordant is yellow orange, which is brighter under tungsten light. However, the dyeing fastness is poor.

5. Printing: Chrysoidine can be used for direct printing. The ground color is better with oxidized whitening, and the effect of reducing whitening is poor. 6. Other: It can be used for dyeing leather, paper, feather, grass, wood, bamboo and other products.

Packing:

20 or 25kg/compound bag, carton box, iron drum, fiber durm for powder dye and 1000kg/tank for liquid dye
