• Chemische Eigenschaften

  orange to red-brown crystalline powder

• Verwenden

  1,4-Dihydroxyanthraquinone, also known as quinizarin, is of great importance in manufacturing disperse, acid, and vat dyes.

• Verwenden

  1,4-Dihydroxyanthraquinone is used to color gasoline and some heating oils. It is used as an intermediate for the synthesis of indanthrene- and alizarin-derived dyes. It is also used to form lake pigments with calcium, barium and lead. It may be used in the synthesis of cyclopentanoids by cyclization of α,β-unsaturated aldehyde with 1,4-Dihydroxyanthraquinone. It has been studied as a long range emissive ratiometric fluorescent probe for live cell imaging.

• Verwenden

  Antioxidant in synthetic lubricants, dyes.

• Definition

  ChEBI: Quinizarin is a dihydroxyanthraquinone having the two hydroxy substituents at the 1- and 4-positions; formally derived from anthraquinone by replacement of two hydrogen atoms by hydroxy groups It has a role as a dye.

• Manufacturing Process

  1,4-Dihydroxyanthraquinone is commonly known as Quinizarin.
  (a) Boric acid, boric acid and mercury, boric acid and nitrous acid or nitrous acid and mercury in the presence of Anthracene-9,10-dione with sulfuric acid;
  (b) In the presence of boric acid and nitrous acid, treated with sulfuric acid 1-Hydroxyanthracene-9,10-dione or 2-Hydroxyanthracene-9,10-dione,
