| | クロラゾール ブラック E Usage And Synthesis |
| 外観 | 黒色粉末～結晶 | | 溶解性 | 水、エタノール及びアセトンに混和する。 | | 解説 | 木綿用の黒色直接染料で，かつては大量に使用されたが，現在では反応染料の出現と中間体であるベンジジンの発癌性のために製造が中止され，歴史的に著名な染料となった。原料はベンジジン，m‐フェニレンジアミン，H酸およびアニリンで，中性浴よりセルロース繊維を1浴で黒色に染めることができる。堅牢度はやや低く，耐光堅牢度3級，洗濯堅牢度2級程度である(染色堅牢度)。発癌性の低いジアニシジン(3,3’‐ジメトキシベンジジン)を用いて合成した代替品がある。
株式会社平凡社 世界大百科事典 第２版について 情報 | | 用途 | 染料 | | 用途 | 原虫のコーン染色用。 | | 説明 | Direct black 38 is a black powder. An AZOcompound. Molecular weight= 781.78; Freezing/Meltingpoint $ 400℃. Hazard Identification (based on NFPA-704M Rating System): Health 1, Flammability 1, Reactivity 0.Slightly soluble in water. | | 化学的特性 | black crystalline powder | | 使用 | Chlorozol Black E is a chitin-specific stain and used to detect fungal filaments. Dyes and metabolites, Environmental Testing.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list. | | 製造方法 | 4-(4-Aminophenyl)benzenamine double nitriding, in acid conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, aniline diazo, in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?group of adjacent a coupling, product again with Benzene-1,3-diamine coupling. | | 一般的な説明 | Gray-black microcrystals or black powder. | | 空気と水の反応 | Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water. | | 反応プロフィール | Direct Black 38 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 may form 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 form with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Incompatible with strong acids [NTP, 1992)]. | | 危険性 | Confirmed carcinogen. Moderately toxic
by ingestion and inhalation. An eye irritant. | | 健康ハザード | ACUTE/CHRONIC HAZARDS: Direct Black 38 may be absorbed through the skin. When heated to decomposition it emits very toxic fumes of nitrogen oxides, disodium oxide and sulfur oxides. | | 火災危険 | Flash point data for Direct Black 38 are not available; however, Direct Black 38 is probably combustible. | | 安全性プロファイル | Confirmed carcinogen
with carcinogenic and tumorigenic data.
Moderately toxic by ingestion and
inhalation. An eye irritant. Mutation data
reported. When heated to decomposition it
emits very toxic fumes of NOx, Na2o, and
so2. | | 職業ばく露 | Mutagen; Human Data. Direct black38 is an azo compound and is used to dye fabric, leather,cotton, cellulosic materials, and paper; these are then usedin consumer products. The chemical may be used by artists(CPSC, EPA). The FDA has indicated that although directblack 38 is identified in the literature as a hair-dye component, it is currently not used by the cosmetic industry. Inview of a health hazard alert issued in December 1980 byOSHA, which cautioned workers and employers of the carcinogenic effect of benzidine-derived direct black 38,new nonbenzidine direct black dyes have been developedand used successfully in commercial applications by thepaper and leather industry. These nonbenzidine dyes weredeveloped with the hope of replacing benzidine-based dyesthroughout industry. | | 応急処置 | Skin Contact: Flood all areas of the body thathave contacted the substance with water. Do not wait toremove contaminated clothing; do it under the water stream.Use soap to help assure removal. Isolate contaminatedclothing when removed to prevent contact by others. EyeContact: Remove any contact lenses at once. Flush eyeswell with copious quantities of water or normal saline for atleast 2030 min. Seek medical attention. Inhalation: Leavecontaminated area immediately; breathe fresh air. Properrespiratory protection must be supplied to any rescuers. Ifcoughing, difficult breathing or any other symptomsdevelop, seek medical attention at once, even if symptomsdevelop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk todilute the substance. Assure that the person’s airway isunobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting. | | 貯蔵 | Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Store in a cool, dry place. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. | | Properties and Applications | black. Palm black powder. Soluble in water for green light black, solubility 40 g/l (85 ℃), and adequate soluble in alcohol for green light blue-black, right amount soluble in soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid is a deep red in blue, diluted Purple dark reddish brown for to red light black precipitation; In nitric acid solution for yellow brown (not completely); In strong hydrochloric acid for dark red light black solution (don’t). The dye solution to join strong hydrochloric acid for Purple dark reddish brown, precipitation; Concentrated sodium hydroxide solution is generated gray light blue precipitaten. Cellulose fiber of dyeing, the dye absorption rate as well, in 80 ℃ temperature when the biggest affinity. Can discharge. Used for cotton, viscose, silk, polyamide fiber and its blending fabric, leather, wood, biological and plastic color, also used as the raw material of black ink.

| | 不和合性 | Azo dyes can form explosive mixtures inair, especially if sensitized with metal salts and/or strongacids. Contact with alkali metals forms explosive gases.Contact with oxidizers and reducing agents forms toxicfumes and gases; also with acids, acryl halides, aldehydes,amides, carbamates, cyanides, epoxides, fluorides (inorganic), halogenated organic materials, isocyanates, ketones,metals, nitrides, peroxides, phenols. May form explosivemixtures with oxidizers, metal salts, peroxides, and sulfides. |
