Dark red powder, soluble in water, but soluble in ethanol red solution, slightly soluble in acetone. In a purple color of sulfuric acid, and it will dilute to product red precipitate; Nitric acid in deep red, turn red after yellow. Its water solution and strong hydrochloric acid red; Add sodium hydroxide fluid shows red orange brown. Dyeing copper ions in slightly dark color. Good levelness. Mainly used in strong acid dye in bath dyeing wool, wool fabrics can be in silk fabric, polyamide fiber and printing.

Appearance is dark red powder. Soluble in water, soluble in ethanol, red solution, slightly soluble in acetone. When concentrated sulfuric acid is purple, it will be diluted to give magenta precipitation; in case of concentrated nitric acid, it will be dark red, then turn red. Light yellow. Its aqueous solution is blue red, concentrated hydrochloric acid is red; sodium hydroxide solution is red orange brown.

Acid Red 14 Application:

The Barium salt can be used as organic pigment use. Also can be used in the manufacture color amylum, ink and used for leather, paper, soap, wood, electrical-controlled silver, medicine, biology and cosmetics shading.

Acid Red 14 Use condition:

1. It is mainly used for dyeing wool in strong acid dyeing bath. It can be printed on wool, nylon and silk fabric. Its strontium salt can be used as organic pigment. It can also be used in the manufacture of lake, ink and leather, paper, soap, Coloring of wood, anodized aluminum, medical organisms and cosmetics.

2. Wool dyeing is carried out in a strong acid bath, the pH value of the dyeing solution is adjusted to 2~4, and the Canadian dollar powder is used as a retarding agent. The highest dyeing temperature when using acetic acid as the dyeing agent is 95~100 °C; It is carried out in an acetic acid bath. When the wool is dyed in the same bath as the various fibers, the apparent color depth of the nylon is similar to that of the wool, the silk is slightly shallow, and the cellulose fibers are not stained.

3. It is discolored by the influence of metal salt during dyeing, so this dye is generally not used as the main dye when dyeing red.

Packing:

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