Acid Red 18 Chemical Properties,Uses,Production
Chemical Properties
Deep red powder
Preparation
4-Aminonaphthalene-1-sulfonic acid diazo, and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling.
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.]
