| | PONCEAU SX Usage And Synthesis |
| Uses | Dye in externally applied drugs, cosmetics; food colorant in maraschino cherries. | | Preparation | 2,4-Dimethyl-5-aminobenzenesulfonic acid diazo, coupled with the 4-Hydroxynaphthalene-1-sulfonic acid. | | General Description | Red crystals. Aqueous solution is yellowish-red. | | Air & Water Reactions | Azo dyes can be explosive when suspended in air at specific concentrations. Water soluble. | | Reactivity Profile | PONCEAU SX is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class 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. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. | | Fire Hazard | Flash point data for PONCEAU SX are not available; however, PONCEAU SX is probably combustible. | | Flammability and Explosibility | Nonflammable | | Properties and Applications | bright yellow light red to red. Soluble in water for yellow light red, slightly soluble in alcohol. The strong sulfuric acid is a deep in the red, red after diluted precipitation; In nitric acid solution for orange, then become yellow. The dye solution to join strong hydrochloric acid red slightly deepen; Add thick sodium hydroxide solution for orange. |
