| | 4-アミノアゾベンゼン Usage And Synthesis |
| 外観 | 赤黄色〜赤褐色, 結晶性粉末〜粉末 | | 溶解性 | 水に難溶 ( ＜0.1 g/100 mL at 19℃)。 エーテル, 熱エタノールに可溶。エタノールに溶け、水に溶けにくい。 | | 解説 | p-アミノアゾベンゼン．過剰のアニリンと塩酸との混合物に亜硝酸ナトリウムを作用させてつくられる．橙色の針状晶．融点127 ℃．エタノール，ベンゼンなどに可溶．アゾ染料の合成中間体として用いられる． | | 用途 | 塩として染色、アシッドイェロー、ジアゾ染料の合成中間体、二塩基酸の評価試薬(比色分析) | | 用途 | 活性アルミナの活性度検定用、クロマトグラフ用。 | | 説明 | This azoic coloring can be reduced in paraphenylenediamine
(PPD). It ean be found in some semipermanent
hair dyes, and patch tests are frequently
positive (about 30%) in hairdressers with hand
dermatitis. Because of cross-sensitivity, the detection
of sensitization to p-aminoazobenzene may be assumed
by a PPD test. | | 化学的特性 | 4-Aminoazobenzene forms yellow to tan crystals or orange needles. | | 化学的特性 | powder | | 使用 | as a dye for lacquer, varnish, wax products, oi! stains and styrene res ins; in insecticides; used as an intermediate in the
manufacture of Acid Yellow, diazo dyes and indulines. | | 使用 | In form of its salts in dyeing; intermediate in manufacture of Acid Yellow, diazo dyes and indulines. | | 製造方法 | commonly known as Aniline Yellow. (a) aniline?hydrochloride solution added to a aniline?diazonium salt, and slowly, until aniline?diazonium salt salt disappear so far. Then in contain a small amount of aniline?hydrochloride aniline?solution will product (Diazoaminobenzene) 30 ~ 40 ℃ heating 2 ~ 3 hours,??acidified to form 4-(Phenyldiazenyl)benzenamine??hydrochloride and crystalline precipitates. In order to obtain 4-(Phenyldiazenyl)benzenamine?times the company, and then 4-(Phenyldiazenyl)benzenamine hydrochloride dissolved in water and mercerized. (B) aniline?diazotization and coupling anilino-methanesulfonic acid, sodium hydroxide solution and then with boiled together, hydrolyzed mesylate. | | 定義 | ChEBI: Azobenzene substituted at one of the 4-positions by an amino group. | | 一般的な説明 | Odorless brownish-yellow needles with bluish coating, or an orange powder. | | 空気と水の反応 | Dust may form an explosive mixture in air. Insoluble in water. | | 反応プロフィール | 4-AMINOAZOBENZENE can detonate, particularly if sensitized by the presence of metal salts or strong acids. May form toxic gases 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. May form flammable gases with alkali metals. May react explosively with strong oxidizing agents, metal salts, peroxides, and sulfides. Emits toxic fumes of oxides of nitrogen when heated to decomposition (over 350°C) [Sax, 2nd ed., 1965, p. 417]. | | 危険性 | Possible carcinogen. | | 火災危険 | Flash point data for 4-AMINOAZOBENZENE are not available; however, 4-AMINOAZOBENZENE is probably combustible. | | 接触アレルゲン | This azoic coloring can be reduced in para-phenylenediamine
(PPD). It can be found in some semi-permanent
hair dyes and patch tests are frequently positive
(about 30%) in hairdressers with hand dermatitis.
Because of hydrolysis of the azo bond, the detection of
sensitization to p-aminoazobenzene may be assumed
by a PPD test. | | 安全性プロファイル | Confirmed carcinogen with experimental neoplastigenic and tumorigenic data. Poison by intraperitoneal route. An experimental teratogen. Mutation data reported. Used as a dye for lacquer, varnish, wax products, oil stains, and styrene resins. When heated to decomposition it emits toxic fumes of NOx. See also AMINES | | 職業ばく露 | An azo compound used in form of salts in dyeing; used as intermediate in manufacture of acid yellow and diazo dyes; in insecticides, waxes, lacquers, varnishes, stains, styrene resins | | 輸送方法 | UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required | | 純化方法 | Crystallise this dye from EtOH, CCl4, pet ether/*C6H6, or a MeOH/H2O mixture. [Beilstein 16 IV 445.] | | Properties and Applications | green light yellow to red light yellow. Melting point is 127.5 ℃, its hydrochloride for blue crystal. Soluble in ethanol, slightly soluble in water for yellow. In concentrated sulfuric acid for brown, red after diluted solution; In hydrochloric acid solution for red, boil color disappear. Used for alcohol soluble paint, varnish, paraffin wax, oil, synthetic resin coloring.

| | 不和合性 | Dust may form explosive mixture with air. Azo 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. This chemicalis sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents |
