Chemische Eigenschaften

CLEAR COLORLESS TO YELLOWISH LIQUID

Verwenden

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.

Vorbereitung Methode

Dimethyl cyanamide is made by the reaction of nitromethane with tris(dimethylamino) arsine.

Allgemeine Beschreibung

Clear liquid.

Air & Water Reaktionen

Reacts with water to form cyanide gas

Reaktivit?t anzeigen

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.

Brandgefahr

DIMETHYLCYANAMIDE is combustible.

Sicherheitsprofil

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
