일반 설명
A yellow to yellowish red gas. Liquefies at -5.5°C. Very toxic by inhalation. Noncombustible, but accelerates burning of combustible material. Decomposed by water to form corrosive hydrochloric acid. Vapors heavier than air. Prolonged exposure to fire or heat can cause containers to rupture violently and rocket .
제조 및 합성 방법
제조 방법
Nitrosyl chloride can be prepared by the reaction of nitric oxide with chlorine: 2NO + Cl2 → 2ClNOAlso, nitrosyl chloride is produced by the action of chlorine on sodium nitrate; or by the reaction of nitrosyl sulfuric acid with hydrochloric acid: NaNO3 + Cl2 → ClNO + NaClO2 ONHSO4 + HCl → ClNO + H2 SO4Nitrosyl chloride also is obtained as a byproduct in the manufacture of potassium nitrate from potassium chloride and nitric acid:In the above preparative method, nitrosyl chloride must be separated from nitric acid; otherwise, in the presence of pure and excess nitric acid, it can decompose to nitrogen dioxide and chlorine:2ClNO + HNO3 → 6NO2 + Cl2 +2H2OAlso, nitrosyl chloride can be synthesized from its elements by heating nitrogen, oxygen and chlorine gas at 400°C: N2 + O2 + Cl2 → 2ClNOFaraday obtained nitrosyl chloride by dissolving palladium in a mixture of hydrochloric and nitric acids (Faraday, M. Trans. Roy. Soc. (London), Vol. 136, pp. 48, 1846): Pd + HNO3 + 3HCl → PdCl2 + ClNO + 2H2O.
