ジメチルシアナミド 化学特性,用途語,生産方法
外観
無色～うすい黄色透明液体
用途
化学中間体、溶媒
化学的特性
CLEAR COLORLESS TO YELLOWISH LIQUID
使用
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.
調製方法
Dimethyl cyanamide is made by the reaction of nitromethane
with tris(dimethylamino) arsine.
一般的な説明
Clear liquid.
空気と水の反応
Reacts with water to form cyanide gas
反応プロフィール
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.
健康ハザード
ACUTE/CHRONIC HAZARDS: DIMETHYLCYANAMIDE is an irritant. It reacts with water to produce toxic and flammable vapors.
火災危険
DIMETHYLCYANAMIDE is combustible.
安全性プロファイル
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
