Uses and synthesis of 1,4-Diamino anthraquinone powder

1,4-Diamino anthraquinone powder Dark purple needle crystals (in pyridine) or purple crystals. Soluble in benzene, pyridine, nitrobenzene, aniline, slightly soluble in hot acetic acid, ethanol. 1,4-Diamino anthraquinone CAS 128-95-0 is widely used for reducing grey BG, dispersive turquoisant blue HBF and acid dyes. 1,4-Diamino anthraquinone Raw Materials were synthesized by condensation of hydroquinone and anhydride to produce 1, 4-dihydroxy-anthraquinone, and then aminated to produce 1, 4-diaminoanthraquinone leuchromosome, and then oxidized with fuming sulfuric acid.

Applications/Functions of 1,4-Diamino anthraquinone powder

• 1,4-Diamino anthraquinone powder plays a vital role in the dye and pigment industry. As an important intermediate, it connects basic chemical raw materials and various dyes and pigments with specific properties. Its application enables us to obtain a variety of colorants with bright colors and excellent properties, which are widely used in textiles, coatings, plastics and other fields.
• 1,4-Diaminoanthraquinone is a key intermediate in the synthesis of a variety of anthraquinone dyes, especially dyes used for textile dyeing and printing. These dyes generally have the following advantages:
  Bright colors: can produce a variety of bright colors, especially in shades such as blue, purple and green.
  Good fastness: has good fastness properties such as light resistance, washing resistance and friction resistance, making the dyed fabrics not easy to fade.
  Good chemical stability: the chemical structure of anthraquinone dyes is relatively stable and is not easily affected by the external environment
