| | ポンソー SX Usage And Synthesis |
| 外観 | 赤黄色～赤色, 粉末 | | 定義 | 本品は、平成15年厚労省令第126号に示される赤色504号又はそのアルミニウムレーキである。 | | 溶解性 | 水に溶ける。 | | 用途 | 染料、試験研究用。 | | 化粧品の成分用途 | 着色剤 | | 使用 | Dye in externally applied drugs, cosmetics; food colorant in maraschino cherries. | | 製造方法 | 2,4-Dimethyl-5-aminobenzenesulfonic acid diazo, coupled with the 4-Hydroxynaphthalene-1-sulfonic acid. | | 一般的な説明 | Red crystals. Aqueous solution is yellowish-red. | | 空気と水の反応 | Azo dyes can be explosive when suspended in air at specific concentrations. Water soluble. | | 反応プロフィール | 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. | | 火災危険 | Flash point data for PONCEAU SX are not available; however, PONCEAU SX is probably combustible. | | 燃焼性と爆発性 | Non flammable | | 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. |
