Malononitrile Usage And Synthesis

Description	Malonitrile, also known as Malononitrile, is an aliphatic nitrile that can release cyanide through chemical or biological transformation. It was also used decades ago for treating certain forms of mental illness.
Chemical Properties	Malononitrile is a white powder or colorless, odorless crystalline substance. It may polymerize violently on prolonged heating at 130°C or at lower temperatures on contact with strong bases.
Uses	Malononitrile 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
Uses	The 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.
Definition	ChEBI: Malononitrile is a dinitrile that is methane substituted by two cyano groups. It is a dinitrile and an aliphatic nitrile.
Production Methods	Malononitrile can be synthesized by a continuous method where preheated acetonitrile and cyanogen chloride are introduced into a tube reactor until the reaction mixture reaches a temperature of about 780°C. Another way to prepare malononitrile is by reacting phosphorus pentachloride with cyanoacetamide, or by using phosphorus pentoxide to react with malonamide or cyanoacetamide. DOI: 10.15227/orgsyn.010.0066
General Description	A 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 Reactions	Soluble in water.
Reactivity Profile	Malononitrile 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].
