75-72-9 Usage

General Description

Chlorotrifluoromethane, also known as CFC-13, is a chemical compound with the formula CF3Cl. It is a colorless, odorless gas that was commonly used as a refrigerant and propellant in aerosol sprays. However, it has been phased out of use due to its contribution to ozone depletion and global warming. CFC-13 is considered a potent greenhouse gas with a high potential to cause harm to the environment. Its production and use are regulated under the Montreal Protocol, an international treaty aimed at protecting the ozone layer.

Check Digit Verification of cas no

The CAS Registry Mumber 75-72-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75-72:
(4*7)+(3*5)+(2*7)+(1*2)=59
59 % 10 = 9
So 75-72-9 is a valid CAS Registry Number.

EXPLOSIVE REACTIONS OF LIQUID MIXTURES OF CHLORINE TRIFLUORIDE WITH HYDROCARBONS AND HALOCARBONS

Brower, K. R.

, p. 333 - 350 (1986)

Combinations of liquid ClF3 with several hydrocarbons and halocarbons have been caused to explode by sudden mixing at various temperatures from 25 degC downward.The mixtures occasionally detonate.By fast recording of pressure, flame ionization, and carbon deposition it is found that mixtures derived from all of the fuels tested except perfluorohexane initiate in less than 1 ms at all temperatures down -70 degC.An ionic mechanism is proposed.Analysis of the explosion gases indicates that all chemical bonds including C-H are labilized owing to the extremely high temperature.Calorimetric measurements agree with calculated heats of explosion.

PROCESSES FOR PRODUCING TRIFLUOROIODOMETHANE

-

Paragraph 0053-0055, (2020/03/09)

The present disclosure provides a gas-phase process for producing trifluoroiodomethane, the process comprising providing a reactant stream comprising hydrogen iodide and trifluoroacetyl halide selected from the group consisting of trifluoroacetyl chloride, trifluoroacetyl fluoride, trifluoroacetyl bromide, and combinations thereof, and reacting the reactant stream in the presence of a catalyst at a temperature from about 200° C. to about 600° C. to produce a product stream comprising the trifluoroiodomethane.

One-Step Process for Hexafluoro-2-Butene

-

Paragraph 0033; 0034, (2016/02/18)

Disclosed is a one step process for making of 1,1,1,4,4,4-hexafluoro-2-butene. More specifically, the present invention provides a process for making hexafluoro-2-butene, continuously, from 2-chloro-3,3,3-trifluoropronene using Fe2O3/NiO impregnated carbon catalyst at 600° to 650° C.

Chemical ionization using CF3+: Efficient detection of small alkanes and fluorocarbons

Dehon, Christophe,Lemaire, Jo?l,Heninger, Michel,Chaput, Aurélie,Mestdagh, Hélène

experimental part, p. 113 - 119 (2011/08/21)

The trifluoromethyl ion CF3+ is evaluated as a chemical ionization (CI) precursor in a compact Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer. It reacts with alkanes by hydride abstraction allowing characterization and quantification of alkanes up to C4 and cyclic. With larger alkanes fragmentation occurs. Fluorocarbons react by fluoride abstraction. Rate coefficients have been measured for reaction with alkanes, fluoroalkanes, chlorofluoroalkanes as well as several common VOCs. Use of CF3+ for trace analysis in air has been tested on an air sample containing traces of acetone, toluene, benzene and cyclohexane. The results are consistent with those obtained with H3O+ precursor and allow additional cyclohexane quantification.
