MSDS Information

• Diphenylnitrosamine

N-ニトロソジフェニルアミン 化学特性,用途語,生産方法

• 外観

  黄色～暗褐色又は暗緑褐色, 結晶～粉末

• 溶解性

  水に不溶。アセトン, メタノールに可溶。エタノールに難溶。

• 用途

  有機ゴム(スコーチ防止剤),染料中間体,安定剤,焼け防止剤 (NITE CHRIP)

• 化学的特性

  N-Nitrosodiphenylamine is a yellow to orangebrown crystalline solid. Soluble in acetone, benzene, ethyl acetate, dichloromethane, carbon tetrachloride, ether and carbon disulfide, soluble in hot alcohol, slightly soluble in gasoline, insoluble in water. In the hydrochloric acid methanol solution, a shift reaction can occur, and it can be transformed into p-nitrosodiphenylamine.

• 定義

  ChEBI: N-Nitrosodiphenylamine is a member of phenylhydrazines. It is an industrial compound that formerly used as a vulcanization retarder in the rubber industry.

• 一般的な説明

  N-nitrosodiphenylamine appears as yellow to brown or orange powder or flakes or a black solid. Insoluble in water and denser in water. Hence sinks in water. (NTP, 1992)

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  N-Nitrosodiphenylamine may be sensitive to moisture at elevated temperatures in strongly acidic solutions. May react vigorously with oxidizing agents. May undergo trans-nitrosation reactions with secondary amines .

• 健康ハザード

  ACUTE/CHRONIC HAZARDS: When heated to decomposition N-Nitrosodiphenylamine emits toxic fumes of nitrogen oxides.

• 火災危険

  Flash point data for N-Nitrosodiphenylamine are not available; however, N-Nitrosodiphenylamine is probably combustible.

• 安全性プロファイル

  Moderately toxic by ingestion. An eye irritant. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Human mutation data reported. Dangerous fire hazard when exposed to heat, flame, or oxidzing materials. Can react vigorously with oxidizing materials. When heated to decomposition it emits highly toxic fumes of NOx,. See also NITROSAMINES.

• 職業ばく露

  N-Nitrosodiphenylamine is not a naturally occurring substance; it is a man-made chemical that is no longer produced in the United States. It was used in the manufacture of plastics, resins, rubber and synthetic textiles; to help control processes involved in making rubber products, such as tires and mechanical goods; however, in the early 1980s, the United States manufacturers stopped producing N-nitrosodiphenylamine because new and more efficient chemicals were found to replace its uses. In addition, the use of N-nitrosodiphenylamine had several undesirable side effects which do not occur with the replacement chemicals.

• 発がん性

  Two feeding experiments with NDPhA in rats were totally negative (no tumors). One used daily doses of 120 mg/kg body weight to a total dose of 65 g/kg, and another used a lower dose for only 53 weeks. Another experiment involved larger groups of rats and mice and higher doses. In mice, after 2 years, there was occasional hyperplasia of the bladder mucosa, but no tumors; in rats given 4000 mg NDPhA/kg diet for 2 years, 16/45 males and 40/49 females had transitional cell carcinomas of the bladder. IARC classified NDPhA as not classifiable as to carcinogenicity in humans (Group 3).

• 環境運命予測

  Chemical/Physical. At temperatures greater than 85 °C, technical grades may decompose to nitrogen oxides (IARC, 1978). N-Nitrosodiphenylamine will not hydrolyze because it does not contain a hydrolyzable functional group (Kollig, 1993).
  At influent concentrations of 10, 1.0, 0.1, and 0.01 mg/L, the GAC adsorption capacities were 510, 120, 91, and 38 mg/g, respectively (Dobbs and Cohen, 1980).

• 輸送方法

  UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

• 不和合性

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with reducing agents may form hydrazine; hydrogen bromide. Light sensitive; rapidly decomposes.

• 廃棄物の処理

  Burn in admixture with flammable solvent in furnace equipped with afterburner and scrubber.
