4-НИТРОЗОДИФЕНИЛАМИН химические свойства, назначение, производство
Химические свойства
dark blue to black powder
Использование
Has been used as retardant in vulcanizing rubber.
Общее описание
Green plates with bluish luster or a black powder.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
4-NITROSODIPHENYLAMINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. May react with strong oxidizing agents .
Опасность
Questionable carcinogen.
Пожароопасность
Flash point data for 4-NITROSODIPHENYLAMINE are not available; however, 4-NITROSODIPHENYLAMINE is probably combustible.
Профиль безопасности
Poison by intravenous
route. Suspected carcinogen with
experimental carcinogenic and
neoplastigenic data. Moderately toxic by
ingestion. Mutation data reported. An eye
irritant. When heated to decomposition it
emits toxic fumes of NOx. See also NNITROSO
COMPOUNDS and AMINES.
Возможный контакт
Used as a chemical intermediate for
dyes and pharmaceuticals; in making monomers; and vulcanizing
rubber.

Методы очистки
The amine forms dark green crystals from EtOH or *C6H6 (m 143o). It has UV at max 421nm (EtOH) and is used for detecting Pd and Rh. It is highly toxic and a possible carcinogen.[Beilstein 12 H 207, 12 II 122, 12 III 347, 12 IV 1860..]
Несовместимости
Nitrated organics range from slight to
strong oxidizing agents. If mixed with reducing agents,
including hydrides, sulfides and nitrides, they may begin a
vigorous reaction. Reaction with aliphatic amines can
release carcinogenic nitrosamines. 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.
