空気と水の反応
1,1-diphenylurea may be sensitive to prolonged exposure to air or light. . Insoluble in water.
反応プロフィール
1,1-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).
火災危険
Flash point data for 1,1-diphenylurea are not available, but 1,1-diphenylurea is probably combustible.
