Chlorine pentafluoride, also known as ClF5, is a colorless gas with a sweet odor. It is toxic by inhalation and acts as an irritant to skin, eyes, and mucus membranes. Chlorine pentafluoride is heavier than air and can be corrosive. Under prolonged exposure to fire or intense heat, the containers may violently rupture or rocket. It is used as an oxidizer in propellants.
Chemical Properties:
Colorless gas
Critical temperature: 142.6°C
Enthalpy of vaporization: 22.21 kJ/mol
Specific conductivity: 1.25×10?? ohm·cm?1 [KIR78]

13637-63-3 Usage

Uses

Chlorine pentafluoride does not have any significant commercial application. However, it is used as a fluorinating and oxidizing agent in various industrial processes.
Used in Chemical Industry:
Chlorine pentafluoride is used as a fluorinating agent for the production of certain chemicals, taking advantage of its ability to introduce fluorine atoms into compounds.
Used in Propellant Industry:
Chlorine pentafluoride is used as an oxidizing agent in the production of propellants, where its ability to support combustion and enhance the performance of rocket fuels is utilized.

Air & Water Reactions

Reacts with water or moisture in the air to produce corrosive hydrofluoric acid and toxic chloride gas. Interaction with ice at -100°C, or with water vapor above 0°C is extremely vigorous (Christe, K.O. Inorg. Chem. 1972 11, 1220).

Reactivity Profile

CHLORINE PENTAFLUORIDE is a strong oxidizing agent. Nonflammable, but likely to react vigorously on contact with combustible materials. Reacts violently with lithium, calcium. Emits highly toxic fluoride and chloride fumes when heated to decomposition. Extremely vigorous reaction with water, steam, even ice [Pilipovich D. et al., Inorg. Chem., 1967, 6, p. 1918]. Very vigorous reaction with anhydrous nitric acid even at -100° C [Christie, K. O., Inorg. Chem. 1992, 11, p. 1220].

Health Hazard

TOXIC; may be fatal if inhaled or absorbed through skin. Fire will produce irritating, corrosive and/or toxic gases. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Runoff from fire control may cause pollution.

Health Hazard

Chlorine pentafluoride is a highly toxic gas.It is a severe irritant to the eyes, skin,and mucous membranes. Exposure can causelacrimation, corneal damage, skin burn, andlung damage. Other symptoms are nausea,vomiting, and dyspnea. The liquid is highlycorrosive to skin, causing painful burns.LC50 value, inhalation (rats): 122 ppm/h.

Fire Hazard

Substance does not burn but will support combustion. Vapors from liquefied gas are initially heavier than air and spread along ground. These are strong oxidizers and will react vigorously or explosively with many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react violently with air, moist air and/or water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.

Safety Profile

Poison by inhalation. A corrosive material. Vigorous reaction in contact with water or anhydrous nitric acid. Violent reaction on contact with metals. When heated to decomposition it emits very toxic fumes of Cland F-. See also CHLORINE, FLUORINE, FLUORIDES, and CHLORINE TRIFLUORIDE.

Check Digit Verification of cas no

The CAS Registry Mumber 13637-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,3 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13637-63:
(7*1)+(6*3)+(5*6)+(4*3)+(3*7)+(2*6)+(1*3)=103
103 % 10 = 3
So 13637-63-3 is a valid CAS Registry Number.

Coordinatively saturated complex fluoro cations. Synthesis and characterization of ClF6+AsF6- and ClF6+SbF6-

Christe, Karl O.,Wilson, William W.,Curtis

, p. 3056 - 3060 (2008/10/08)

The reaction of KrF2 with ClF5 and AsF5 in either ClF5 or anhydrous HF solution produces pure ClF6+AsF6-. The white, crystalline solid is stable up to 110°C under a dynamic vacuum and decomposes at higher temperature to ClF5, F2, and AsF5. X-ray powder diffraction patterns show that ClF6+AsF6- (face-centered cubic; a = 9.47 A?) is isotypic with IF6+AsF6-. The reaction of KrF2 with ClF5 and SbF5 produces ClF6+SbF6-; however, this salt could not be isolated in pure form. 19F NMR and vibrational spectra were recorded for the ClF6+ salts, and an anharmonic general valence force field was computed for ClF6+ by using the observed frequencies and the 35Cl-37Cl isotopic shift of v3 (F1u). General methods for the syntheses of coordinatively saturated complex fluoro cations are compared and discussed.

The chemistry of platinum hexafluoride. II. Reactions with chlorine trifluoride, bromine pentafluoride, and tetrafluorohydrazine

Gortsema,Toeniskoetter

, p. 1925 - 1927 (2008/10/08)

Platinum hexafluoride reacts with chlorine trifluoride to give chlorine pentafluoride and the solid ClF3PtF5. The infrared spectrum indicates that ClF3PtF5 exists in the ionic form ClF2+PtF6-. Platinum hexafluoride reacts with bromine pentafluoride to give fluorine and a black viscous liquid, but no higher bromine fluorides are formed. Tetrafluorohydrazine and platinum hexafluoride react to give nitrogen trifluoride and PtF4-5.
