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.
