ACID RED 1 Chemical Properties,Usage,Production

Chemical Properties Dark red powder
Uses A useful stain with color index of 18050.
Uses Acid Red 1 is a synthetic red azo dye used as food additive. Studies have shown that Red Acid 1 is converted to toxic compound aniline and may ultimately interfere with blood haemoglobin.
Definition ChEBI: An organic sodium salt that is the disodium salt of 5-acetamido-4-hydroxy-3-(phenyldiazenyl)naphthalene-2,7-disulfonic acid.
Preparation aniline diazo, and 4-Acetamido-5-hydroxynaphthalene-2,7-disulfonic acid coupling.
Flammability and Explosibility Non flammable
Purification Methods Salt it out three times with sodium acetate, then repeatedly extract it with EtOH. See Solochrome Violet R in “Aromatic compounds”, Chapter 4. [McGrew & Schneider J Am Chem Soc 72 2547 1950.]

Properties and Applications colourful red blue light. Red powder. Soluble in water solution for big red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. Meet strong sulfuric acid is blue light red, it will be diluted in a yellow after red; Meet nitric acid solution is orange turn orange; Meet strong hydrochloric acid generation red precipitation, dilute it dissolve. The aqueous solution of dyes and strong hydrochloric acid is product red; Add sodium hydroxide is orange brown. Copper ions in dyeing and dark blue colour and lustre to take; Iron ion in color with blue and light. Good levelness. Mainly used in strong acid medium in the wool dyeing and the piece dyed wool. Can be directly in the wool fabrics, polyamide fiber and fabric silk printing. Also can be used for leather dyeing, also can be used in the manufacture of color amylum, cosmetics, paper, soap and timber colorants, is used to make the ink. The Barium salt can be used in organic pigments.
