DIMETHYLCYANAMIDE Usage And Synthesis
Chemical Properties
CLEAR COLORLESS TO YELLOWISH LIQUID
Uses
Dimethylcyanamide in the presence of tetrachlorosilane and zinc chloride is used as a promoter for one-pot, three component synthesis of a novel series of 1,3-oxazines. Being a dialkylcyanamide, it has been proved to be a more reactive substrate toward metal-mediated nucleophilic addition than alkylcyanides.
Production Methods
Dimethyl cyanamide is made by the reaction of nitromethane with tris(dimethylamino) arsine.
General Description
Clear liquid.
Air & Water Reactions
Reacts with water to form cyanide gas
Reactivity Profile
Nitriles, such as DIMETHYLCYANAMIDE, 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. DIMETHYLCYANAMIDE reacts with oxidizers, water, or steam.
Health Hazard
ACUTE/CHRONIC HAZARDS: DIMETHYLCYANAMIDE is an irritant. It reacts with water to produce toxic and flammable vapors.
Fire Hazard
DIMETHYLCYANAMIDE is combustible.
Safety Profile
Poison by ingestion, skin contact, and intraperitoneal routes. Moderately toxic by inhalation. Flammable when exposed to heat, flame, or oxidzers. Can react with oxidzing materials. To fight fire, use foam, CO2, or dry chemical. When heated to decomposition or in reaction with water or steam it produces toxic fumes of NOx, and CNand flammable vapors. See also CYANIDE
