• Definition

• Allgemeine Beschreibung

  A colorless gas or green liquid with a pungent odor. Boils at 53°F. CHLORINE TRIFLUORIDE reacts with water to form chlorine and hydrofluoric acid with release of heat. Contact with organic materials may result in spontaneous ignition. CHLORINE TRIFLUORIDE is corrosive to metals and tissue. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects. Under prolonged exposure to fire or intense heat the container may violently rupture and rocket.

• Air & Water Reaktionen

  A violent reaction occurs with water or ice generating acidic HF and chlorine, [Sidgwick, 1156(1950)]. The release of CHLORINE TRIFLUORIDE to the atmosphere rapidly generates two toxic reaction products: HF and Chlorine Dioxide, [Lombardi, D.A. and M.D. Cheng 1996. "Modeling Accidental Releases of CHLORINE TRIFLUORIDE to the Atmosphere," Paper No. 96-WP66B.02, presented at the 89th Annual Meeting of the Air and Waste Management Association, Nashville, Tennessee, June 23-26].

• Reaktivität anzeigen

  CHLORINE TRIFLUORIDE is a low-boiling liquid (b.p. 12° C), in gaseous state irritating and toxic. A highly reactive oxidant reagent, spontaneously flammable, used as a rocket propellant. Incompatible with fuels, nitro compounds. Interaction with water is violent and may be explosive, even with ice [Sidgwick, 1950, p. 1156]. Immediate explosive reaction with hydrocarbons or halocarbons even at -70° C [Brower, K. R., J. Fluorine Chem., 1986, 31, p. 333]. Solution with carbon tetrachloride capable of detonation, solutions with nitroaryl compounds (TNT, hexanitrobiphenyl) or highly chlorinated compounds are extremely shock-sensitive. Violent, sometimes explosive reaction with hydrogen containing materials, e.g., acetic acid, ammonia, benzene, ether, coal gas, hydrogen, hydrogen sulfide, methane, or fluoroamino compounds. Ignition with fibrous materials (cotton, paper, wood). [Mellor, 1956, vol. 2, suppl. 1, p. 155]. Explosive gaseous products (chlorodifluoroamine) formed with ammonium fluoride or ammonium hydrogen fluoride [Gardner, D. M. et al., Inorg., Chem., 1963, 2, p. 413]. Ignition on contact with iodine, boron-containing materials (boron powder, tetraboron carbide, boron-aluminum), fibrous or finely divided refractory materials (asbestos, glass, wool, sand, tungsten carbide). Violent reaction with mineral acids (nitric acid, sulfuric acid), chromium trioxide, ruthenium metal, selenium tetrafluoride. [Bretherick, 5th ed., 1995, p. 1235]. CHLORINE TRIFLUORIDE is a hypergolic oxidizer and contact with a number of metals and their oxides (aluminum, antimony, arsenic, calcium, copper, iridium, iron, lithium, lead, magnesium, molybdenum, osmium, potassium, rhodium, sodium, selenium, silver, tellurium, tin, tungsten, zinc), nonmetals (phosphorus, silicon, sulfur), salts (mercury iodide, potassium iodide, silver, nitrate, potassium carbonate) will result in a violent reaction often followed by ignition [Mellor, 1956, vol. 2, suppl. 1, p. 155; Sidgwick, 1950, p. 1156].

• Hazard

  Explodes in contact with organic materials or with water. Dangerous fire risk. A poison, very toxic, corrosive to skin. Lung damage, eye, and upper respiratory tract irritant. Questionable carcinogen.

• Health Hazard

  Inhalation causes extreme irritation of respiratory tract; pulmonary edema may result. Vapors are very irritating to eyes and skin; liquid causes severe burns.

• Health Hazard

  Chlorine trifluoride is a severe irritant tothe skin, eyes, and mucous membranes.Exposure to this gas can cause lung dam age. A 30-minute exposure to 400 ppm waslethal to rats. It decomposes in the presenceof moisture to chlorine, chlorine dioxide,and hydrogen fluoride, all of which arehighly toxic. Chronic inhalation study on ani mals for a period of 6 months (6 hours/day,5 days/week) indicated that at an exposurelevel of nearly 1 ppm the early symptomswere sneezing, salivation, and expulsionof frothy fluid from the mouth and nose(ACGIH 1986). This progressed to mus cle weakness, pneumonia, and lung damage.Some animals died.
  In humans, exposure to this gas can pro duce severe injury to the eyes, skin, andrespiratory tract, and pulmonary edema. Theliquid is severely corrosive to the skin andeyes. Skin contact can cause painful burns.

• Brandgefahr

  Nonflammable gas; dangerously reactive. Chlorine trifluoride reacts explosively with water, forming hydrogen fluoride and chlo rine. It reacts violently with most elements and common substances. Paper, cloth, wood, glass, wool, charcoal, and graphite burst into flame in contact with the liquid. The vapors, even when diluted, can set fire to organic compounds. Reactions with most metals are vigorous to violent, often caus ing a fire. It catches fire when mixed with phosphorus, arsenic, antimony, silicon, sul fur, selenium, tellurium, tungsten, osmium, and rhodium (Mellor 1946, Suppl. 1956). Among the alkali- and alkaline–earth metals, reaction is violent with potassium at ordinary temperatures, and with sodium, calcium, or magnesium it reacts violently at elevated temperatures. Violent reaction occurs with oxides, sulfides, halides, and carbides of metals, causing flames. Chlorine trifluoride attacks sand, glass, and asbestos. Prolonged contact can ignite glass. Explosive reactions occur with many common gases, includ ing hydrogen, lower hydrocarbons, carbon monoxide, ammonia, hydrogen sulfide, and sulfur dioxide. Reactions with mineral acids and alkalies are violent.
  In case of a small fire involving chlorine trifluoride, use a dry chemical or water spray in large amounts (NFPA 1997). Allow large fires to burn. Avoid contact of chlorine trifluoride with the body or with protective clothing.

If this chemical contacts theskin, remove contaminated clothing and wash immediately620 Chlorine trifluoridewith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting. Medical observation isrecommended for 24-48 h after breathing overexposure, aspulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consideradministering a corticosteroid spray. If frostbite hasoccurred, seek medical attention immediately; do NOT rubthe affected areas or flush them with water.

• läuterung methode

  Impurities include chloryl fluoride, chlorine dioxide and hydrogen fluoride. Passed it first through two U-tubes containing NaF to remove HF, then through a series of traps in which the liquid is fractionally distilled. It can be purified via the KF complex; KClF4, formed by adding excess ClF3 to solid KF in a stainless steel cylinder in a dry-box and shaking overnight. After pumping out the volatile materials, pure ClF3 is obtained by heating the bomb to 100-150o and condensing the evolved gas in a -196o trap [Schack et al. Chem Ind (London) 545 1967]. It attacks glass very vigorously. HIGHLY TOXIC.

• Inkompatibilitäten

  A powerful oxidizer. Keep away from acids. Most combustible materials ignite spontaneously on contact with chlorine trifluoride. Explodes on contact with organic materials. The liquid can explode if mixed with halocarbons or hydrocarbons. It reacts violently with oxidizable materials, finely divided metals and metal oxides; sand, glass, asbestos, silicon-containing compounds. Emits highly toxic fumes on contact with acids. Chlorine trifluoride decomposes above 220C, forming Thermal decomposition products may include hydrogen chloride and HF. Reacts violently with water, forming chlorine gas and hydrofluoric acid.
