Acid Red 18 Chemical Properties,Uses,Production
Chemical Properties
Deep red powder
Uses
Food Red No. 102 is an artificial coloring food additive. Dye. Dyes and metabolites, Environmental Testing
Preparation
4-Aminonaphthalene-1-sulfonic acid diazo, and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling.
Flammability and Explosibility
Non flammable
Biological Activity
New Coccine also referred to as ponceau 4 R, is a synthetic red tar dye. It belongs to the group of azo dyes. New Coccine is extensively used as a food colorant. When the intact dye reaches the intestine, it cause colon specific DNA damage in mice.
Safety Profile
Moderately toxic by intraperitoneal route. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and SOx.
Purification Methods
Dissolve the dye in the minimum quantity of boiling water, filter and enough EtOH is added to precipitate ca 80% of the dye. This process is repeated until a solution of the dye in aqueous 20% pyridine has a constant extinction coefficient. [Beilstein 16 I 306.]
Properties and Applications
red. Red powder. Soluble in water red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. Strong sulfuric acid in purple, will the red orange is diluted; Nitric acid solution in yellow. Its water solution and strong hydrochloric acid red, add sodium hydroxide is brown. Mainly used for wool, silk, polyamide fiber and its blended fabric dyeing, also can be used for leather, paper, plastic, wood, medicine and cosmetics of dyeing, still can make the ink.
