almost white to brown crystalline solid. Succinonitrile [110-61-2], ethylene dicyanide, ethylene cyanide, dicyanoethane, butanedinitrile, NCCH2CH2CN, is a colorless, waxy solid slightly soluble in water and ethanol. Succinonitrile is obtained by addition of hydrogen cyanide to acrylonitrile. Subsequent hydrogenation of succinonitrile yields 1,4-diaminobutane, which reacts with adipic acid to form the new polyamide 46. The polymer, developed by DSM (Netherlands), is marketed under the trade name Stanyl; the latter is reported to have excellent mechanical properties at high temperature.?? ??
Succinonitrile is derived from the interaction of ethylene dibromide and potassium cyanide in the presence of alcohol.?? ??
Colorless to light brown crystals. Colorless waxy soild melting at 57°C. Highly toxic.??? ?? ??
Soluble in water [Hawley].?? ???
Succinonitrile is incompatible with acids and oxidizing agents (such as peroxides and epoxides). Can react violently with strong oxidizing acids. Is hydrolyzed exothermically in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). Can react vigorously with reducing agents.???
A poison.????
Succinonitrile is combustible.Safety Profile
Poison by ingestion, intraperitoneal, and subcutaneous routes. An experimental teratogen. Combustible when exposed to heat or flame. Decomposes exothermically above 195°C. Can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition, or on contact with acid or acid fumes, it emits highly toxic fumes of NOx and CN-. See also NITRILES.Purification Methods
Purify the nitrile by vacuum sublimation, and/or crystallisation from acetone. [Beilstein 2 H 615, 2 IV 1923.]??????? ?? ?? ? ???
