N,N-Diethylaniline is a pale yellow liquid. It is
slightly soluble in water (1.40 g/L at 12°C), and soluble in
alcohol and ether.
용도
N,N-Diethylaniline is used in dyestuffs and in the synthesis of
other intermediates and pharmaceuticals.
일반 설명
A colorless to yellow liquid with a fishlike odor, that is strongly corrosive. Irritating to skin, eyes and mucous membranes and moderately toxic by inhalation, absorption and ingestion. Flash point 185°F. Used in dyes and in the production of organic chemicals.
공기와 물의 반응
Insoluble in water.
반응 프로필
N,N-Diethylaniline 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. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
건강위험
May be fatal if inhaled, swallowed or absorbed through the skin. Vapor or mist is irritant to the eyes, mucous membranes, upper respiratory tract; causes skin irritation. Absorption into the body leads to the formation of methemoglobin which, in sufficient concentration, may cause cyanosis. Onset may be delayed 2-4 hours or longer. Exposure can cause nausea, dizziness, headache, damage to the eyes, and blood effects.
화재위험
Special Hazards of Combustion Products: Emits toxic fumes under fire conditions.
Safety Profile
Moderately toxic by
ingestion and intraperitoneal routes. When
heated to decomposition it emits toxic
fumes of NOx. See also ANILINE DYES.
Purification Methods
Reflux the base for 4hours with half its weight of acetic anhydride, then fractionally distil it under reduced pressure (b 92o/10mm). [Beilstein 12 IV 252.]
