反応プロフィール
N,N'-DIETHYL-N,N'-DIPHENYLUREA (1,3-Diethyl-1,3-diphenylurea) is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). N,N'-DIETHYL-N,N'-DIPHENYLUREA is incompatible with acids and oxidizing agents. N,N'-DIETHYL-N,N'-DIPHENYLUREA reacts violently when severely shocked or exposed to extreme temperatures.
健康ハザード
ACUTE/CHRONIC HAZARDS: N,N'-DIETHYL-N,N'-DIPHENYLUREA may react violently when severely shocked or heated to extreme temperatures.
火災危険
N,N'-DIETHYL-N,N'-DIPHENYLUREA is combustible.
安全性プロファイル
Poison by
intraperitoneal route. Moderately toxic by
ingestion. Combustible when exposed to
heat or flame. Probably a slight explosion
hazard, although it is a component of
smokeless explosive mixtures. When heated o decomposition it burns and emits very
toxic fumes of NOx. To fight fire, use dry
chemical, CO2, spray or mist. An explosion
regulator.
