Malononitrile Usage And Synthesis
Chemical PropertiesSolidified melt
Chemical PropertiesMalononitrile is a white powder or colorless, odorless crystalline substance.
UsesMalononitrile is an important building block for the syntheses of pharmaceuticals (e.g. triamterene, adenine and methotrexate), thiamin (vitamin B1), pesticides dyestuffs for color photography and synthetic fibers (e.g. vinylidene cyanide). Product Data Sheet
UsesMalononitrile is an important building block for the syntheses of pharmaceuticals (e.g. triamterene, adenine and methotrexate), thiamine, pesticides, special dyestuffs for color photography and synthetic fibres. Product Data Sheet
UsesThe chemical properties of malononitrile are determined by the nucleophilicity of the malononitrile anion, formed by deprotonation with relatively weak bases and by the two electrophilic cyano groups.
DefinitionChEBI: A dinitrile that is methane subtituted by two cyano groups.
UsesIn organic synthesis.
General DescriptionA white-colored crystalline solid. Denser than water and soluble in water. Toxic by ingestion and may severely irritate skin and eyes. May polymerize violently if exposed to temperatures above 266°F. Used to make other chemicals.
Air & Water ReactionsSoluble in water.
Reactivity ProfileMalononitrile is a white, low-melting powder (m. p. 30.5° C), toxic, combustible. Violent polymerization on contact with strong bases (sodium hydroxide, potassium hydroxide) or when heated above 130° C. When stored at 70-80° C for 2 months, spontaneous explosion (decomposition) occurred [Bretherick, 5th ed., 1995, p. 394].
HazardToxic by ingestion and inhalation.
Health HazardMetabolized by body to cyanide and thiocyanate; effects of inhalation of toxic fumes will be related to cyanide. Causes brain and heart damage related to lack of cellular oxygen. It is classified as extremely toxic. Probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful, for a 70 kg (150 lb.) person.
Fire HazardWhen heated to decomposition, Malononitrile emits highly toxic fumes (cyanide). May polymerize violently on prolonged heating. Avoid heat. Hazardous polymerization may occur, at prolonged heating at 266F or contact with strong bases at lower temperatures.
Safety ProfilePoison by ingestion, skin contact, subcutaneous, intravenous, and intraperitoneal routes. A severe eye irritant. Combustible when exposed to heat or flame. Polymerizes violently when heated to 130°C or on contact with strong base. May spontaneously explode when stored at 70-80°C. To fight fire, use water, fog, spray, foam. When heated to decomposition it emits toxic fumes of NOx and CN-. See also NITRILES.
Potential ExposureMalononitrile is used in organic synthesis; as a lubricating oil additive; for thiamine synthesis; for pteridine-type anticancer agent synthesis; and in the synthesis of photosensitizers, acrylic fibers, and dyestuffs. It has also been used in the treatment of various forms of mental illness. It has been used as a leaching agent for gold
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and i

Purification MethodsCrystallise the nitrile from water, EtOH, *benzene or chloroform. Distil it in a vacuum from, and store over, P2O5. [Bernasconi et al. J Am Chem Soc 107 7692 1985, Gratenhuis J Am Chem Soc 109 8044 1987, Beilstein 2 IV 1892.]
IncompatibilitiesIncompatible with strong bases. May polymerize violently on prolonged heating @ 129C, or in contact with strong bases at lower temperatures. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.
