概要

Nitrosyl chloride appears as 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.

Excerpt from ERG Guide 125 [Gases - Toxic and/or Corrosive]:

In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.

First Aid Measures · 3 件

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Accidental Release Measures · 2 件

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Do not touch or walk through spilled material.

First Aid · 2 件

INHALATION: remove victim to fresh air; call a doctor; enforce complete rest until doctor arrives; observe at least 24 hours for delayed effects.

General First Aid:

Safe StorageSeparated from incompatible materials. See Chemical Dangers. Cool. Keep in a well-ventilated room.
Exposure Control and Personal Protection · 2 件

· Wear positive pressure self-contained breathing apparatus (SCBA).

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].

毒性情報

Environmental FateAtmospheric fate: Nitrosyl chloride formation may be significant in coastal urban areas because it photolyze rapidly to Cl atoms, and hydrolyzes to HONO, a major OH source; both Cl and OH initiate atmospheric photochemical oxidations.
Adverse EffectsDermatotoxin - Skin burns.

調製方法 · 2 件

製造方法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.

純化方法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.]
