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.

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.

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.
