Nitric oxide - Issankachisso

NO (30.01). Also called nitric oxide. It is obtained by the direct reaction of nitrogen and oxygen at high temperatures, or by the oxidation of ammonia with a platinum catalyst. In nature, it is mainly produced by lightning. In the laboratory, it is obtained by the reaction of copper flakes with sulfuric acid. It is a colorless gas at room temperature. Its melting point is -163.6 °C, its boiling point is -151.8 °C. It is blue in both liquid and solid form. Its dipole moment is 0.16 D. N-O0.114 nm. It has one unpaired electron, is paramagnetic, and reacts well with other free radicals. This property is used to detect free radicals on polymer surfaces. It becomes nitrogen dioxide when exposed to air. It reacts with halogens to form nitrosyl halide NOX. It is one of the nitrogen oxides (NO _x ) that are a problem in air pollution, and is a cause of photochemical smog and acid rain, as well as the destruction of the ozone layer. It is used as an intermediate in the production of nitric acid, as a bleaching agent for rayon, and in the production of semiconductors. It is toxic. [CAS 10102-43-9]

NO(30.01)．酸化窒素ともいう．高温における窒素と酸素の直接反応，白金触媒によるアンモニアの酸化などで得られる．自然界では，主として雷により生じる．実験室では，銅片と硫酸の反応で得られる．室温で無色の気体．融点－163.6 ℃，沸点－151.8 ℃．液体，固体ともに青色．双極子モーメント0.16 D．N-O0.114 nm．不対電子1個をもち，常磁性でほかの遊離基とよく反応する．この性質はポリマー表面の遊離基の検出に利用される．空気に触れると二酸化窒素になる．ハロゲンと反応してハロゲン化ニトロシルNOXをつくる．光化学スモッグや酸性雨の成因，オゾン層破壊の原因ともなり，大気汚染で問題となる窒素酸化物(NO_x)の一つである．硝酸の製造中間体，レーヨンの漂白剤，半導体の製造などに用いられる．有毒．[CAS 10102-43-9]
