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.

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.

Reactivity Profile · 1 件

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].

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].

Fire Fighting Procedures · 1 件

If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use water spray to knock-down vapors.

Cleanup MethodsNEUTRALIZING AGENT FOR ACIDS & CAUSTICS /SMALL SPILLS/: FLUSH WITH WATER. RESIDUAL ACID MAY BE NEUTRALIZED WITH SODA ASH.

Disposal Methods · 1 件

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Spillage Disposal · 1 件

Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove gas with fine water spray. Do NOT absorb in saw-dust or other combustible absorbents.

Preventive Measures · 3 件

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

If material not involved in fire: Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime. Do not use water on material itself.

Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

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.
