니트로실 클로라이드 화학적 특성, 용도, 생산

• 화학적 성질

  Yellow-red liquid or yellow gas.Decomposed by water; dissociates into nitric oxide and chlorine on heating; soluble in fuming sulfuric acid. Nonflammable.

• 물리적 성질

  Yellow gas; heavier than air, density 2.3 (air=1); gas density 2.872 g/L; liquefies at -5.55°C; liquid density 1.273 g/mL; freezes at -59.4°C; critical temperature 167°C; reacts with water; soluble in fuming sulfuric acid.

• 용도

  Synthetic detergents, catalyst, intermediate.

• 제조 방법

  Nitrosyl chloride can be prepared by the reaction of nitric oxide with chlorine: 2NO + Cl₂ → 2ClNO
  Also, 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 SO₄
  Nitrosyl 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 +2H₂O
  Also, nitrosyl chloride can be synthesized from its elements by heating nitrogen, oxygen and chlorine gas at 400°C: N₂ + O₂ + Cl₂ → 2ClNO
  Faraday 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.

• 정의

  One of the oxidizing agents in aqua regia.

• 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 .

• 공기와 물의 반응

  Dissolves into and reacts with moisture in the air or with water to form hydrochloric acid and toxic red oxides of nitrogen.

• 반응 프로필

  Nitrosyl chloride is an oxidizing agent. Dissociates into nitric oxide and chlorine on heating. Gives an explosive reaction when sealed in a tube with a residue of acetone and in the presence of platinum catalyst [Chem. Eng. News 35(43):60. 1967]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

• 위험도

  Strong irritant, especially to lungs and mucous membranes.

• 건강위험

  Gas is highly toxic. Inhalation causes severe irritation of respiratory tract and damage to mucous membranes. Delayed effects, which include severe pulmonary edema, may not be apparent for several hours.

• 화재위험

  Special Hazards of Combustion Products: Very toxic gases are generated when heated

• Safety Profile

  Poison by inhalation and ingestion. A corrosive irritant to skin, eyes, and mucous membranes. Inhalation may cause pulmonary edema and hemorrhage. Potentially explosive reaction with acetone + platinum. Mixtures with hydrogen + oxygen igmte spontaneously. When heated to decomposition it emits very toxic fumes of Cland NOx.

• 잠재적 노출

  A nitrocompound used as a reagent, catalyst, bleaching agent, and intermediate for making other chemicals.

• 운송 방법

  UN1069 Nitrosyl chloride, Hazard Class: 2.3; Labels 2.3-Poisonous gas, 8-Corrosive material; Inhalation Hazard Zone C

• Purification Methods

  It is an orange gas with a suffocating odour. It has been fractionally distilled at atmospheric pressure in an all-glass, low-temperature still, taking the fraction boiling at -4o and storing it in sealed tubes. Alternatively the gas is dried by CaCl2 and passed through H2SO4 when Cl2 passes on, but NOCl is absorbed to form nitrososulfuric acid (NO.HSO4) which on warming with NaCl evolves pure NOCl [Tilden J Chem Soc 27 630 1874.] It is decomposed by H2O and alkali, and forms compounds with metal chlorides e.g. FeCl3.NOCl. [Coleman Inorg Synth I 55 1939.]

• 비 호환성

  Dissolves into and reacts with moisture in the air or with water forming hydrochloric acid and toxic red oxides of nitrogen. Nitrosyl chloride is a strong oxidizer. Violent reaction with strong acids, alkalis (e.g., sodium hydroxide), ammonia, amines, reducing agents, other strong oxidizers. Elevated temperature may cause explosive decomposition. Dissociates into nitric oxide and chlorine on heating. Corrosive to most metals. Attacks some plastics, rubber, and coatings.

• 폐기물 처리

  Return refillable compressed gas cylinders to supplier. Use a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
