Acid Red 18 Chemical Properties,Usage,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

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.

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.
