Chemische Eigenschaften
3-Chloropropionitrile is a combustible, colorless liquid with an acrid odor
Verwenden
In pharmaceutical and polymer synthesis. Combines the reactivity of a nitrile and an alkyl halide. Because of the cyano group the chlorine atom is more reactive than in ordinary alkyl halides.
Vorbereitung Methode
3-Chloropropionitrile [542-76-7], 3-chloropropanenitrile, b-chloropropionitrile, ClCH2 CH2CN, Mr 89.53, mp-51℃, bp 175 –176℃ (101.3 kPa), n20D 1.4360, d204 1.1573, is a colorless liquid miscible with acetone, benzene, ethanol and diethyl ether. It can be obtained by hydrochlorination of acrylonitrile with hydrochloric acid [49] and is used as an organic intermediate in the synthesis of the H2-receptor famotidine.
Allgemeine Beschreibung
Colorless liquid with a characteristic acrid odor. Used in pharmaceutical and polymer synthesis.
Reaktivität anzeigen
Toxic gas (hydrogen chloride) is released when the compound is heated above 266 F. When heated to decomposition, 3-Chloropropiononitrile emits very toxic fumes of chlorine- containing compounds and nitrogen oxides. Avoid heat. [EPA, 1998].
Hazard
Toxic by ingestion, inhalation, and skin
contact. Combustible.
Health Hazard
Toxic effects are a result of systemic cyanide poisoning. (Non-Specific -- Cyanide) Few poisons are more rapidly lethal. Average oral lethal dose for hydrogen cyanide is approximately 60-90 mg (corresponds to 200 mg of potassium cyanide). Cause of death is lack of oxygen to the body's cells (especially the brain and heart) as a result of the chemical inhibiting cell enzymes.
Brandgefahr
Toxic gas (hydrogen chloride) is released when the compound is heated above 266F. When heated to decomposition, 3-Chloropropiononitrile emits very toxic fumes of chlorine- containing compounds and nitrogen oxides. Avoid heat.
mögliche Exposition
This material is used in pharmaceutical manufacture and in polymer synthesis.
