| | C.I. 14720 Usage And Synthesis |
| Uses | Azo Rubine is an synthetic red food dye and is used for the purposes where food is heat-treated after fermentation. | | Preparation | 4-Aminonaphthalene-1-sulfonic acid diazo, coupled with the 4-Hydroxynaphthalene-1-sulfonic acid. | | Definition | ChEBI: Carmoisine is an organic molecular entity. | | General Description | Reddish-brown crystals or dark maroon powder. | | Air & Water Reactions | Can be explosive as a dust in air at certain concentrations. Moderately soluble in water. | | Reactivity Profile | C.I. 14720 may form toxic gases with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. May form flammable gases with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. | | Health Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition C.I. 14720 emits very toxic fumes of sulfur oxides, nitrogen oxides and Na2O. | | Fire Hazard | Flash point data for C.I. 14720 are not available; however, C.I. 14720 is probably combustible. | | Flammability and Explosibility | Notclassified | | Properties and Applications | blue-ray red. 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. 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.
