|Section2= |Section3= }} Phosgene oxime, or CX, is an organic compound with the formula Cl2CNOH. It is a potent chemical weapon, specifically a nettle agent. The compound itself is a colorless solid, but impure samples are often yellowish liquids. It has a strong, disagreeable odor and a violently irritating vapor. ==Preparation and reactions== Phosgene oxime can be prepared by reduction of chloropicrin: : Cl3CNO2 + 2 Sn + 5 HCl + H2O → Cl2C=N−OH + 2 H3O() The observation of a transient violet color in the reaction suggests intermediate formation of trichloronitrosomethane (Cl3CNO). Early preparations, using stannous chloride as the reductant, also started with chloropicrin. The compound is electrophilic and thus sensitive to nucleophiles, including base hydrolysis: :Cl2CNOH + 2 NaOH → CO2 + NH2OH + 2 NaCl + H2O Similar processes provide an easy way to destroy this dangerous compound. Hydrazine converts it to HCN and N2. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phosgene oxime」の詳細全文を読む スポンサード リンク
