The radiation chemistry of acyclic hydrofluoro and perhalogenated ether and hydrocarbon compounds

The radiolytic stability of some hydrofluoroethers and hydrofluorocarbons was investigated and compared with those of perfluoropolyethers (PFPEs) and the CCl2FCClF2 (CFC 113). The experimental results indicate that stability depends mainly on the relative abundance of hydrogen atoms in the molecule; however, a significant role is played also by the chemical structure (i.e. the relative positions of the hydrogen atoms in the molecule). As a result, molecules containing hydrogen atoms as -OCF2H chain ends show a higher stability compared with the other hydrofluoro compounds. Based on the analysis of the end products and on the nature of radicals detected by EPR, radiolysis mechanisms are proposed and discussed. Due to their high dipole moments the hydrofluoro compounds and CCl2FCClF2 degrade mainly through an ionic mechanism.

PROCESSES FOR PRODUCING TRIFLUOROIODOMETHANE

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.

Cu-catalyzed chlorotrifluoromethylation of alkenes with CF3SO2Cl

Although CF3SO2Cl is an efficient chlorotrifluoromethylation reagent, an expensive transition metal complex usually has to be used. We found that CuCl2-catalyzed chlorotrifluoromethylation of alkenes with CF3SO2Cl occurred smoothly under mild conditions. A wide substrate scope and good functional group compatibility were observed.

One-Step Process for Hexafluoro-2-Butene

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.

PROCESS FOR 1-CHLORO-3,3,3-TRIFLUOROPROPENE FROM TRIFLUOROMETHANE

The present invention provides routes for making 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) from commercially available raw materials. More specifically, this invention provides routes for HCFO-1233zd from inexpensive and commercially available trifluoromethane (HFC-23).

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

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.

Methane and methyl chloride as selective reducing agent in the transformation of hydrochlorofluorocarbons or chlorofluorocarbons to hydrofluorocarbons

A gas phase reaction process for producing a hydrofluorocarbon from a hydrochlorofluorocarbon or chlorofluorocarbon reactant by contacting, in the presence of a catalyst, the hydrochlorofluorocarbon or chlorofluorocarbon reactant with a reducing agent selected from methane, methyl chloride and mixtures thereof, to produce the hydrofluorocarbon.

The present invention is related to a method for preparing an amorphous metal fluoride of the formula MX+FX-δ comprising the steps of a) providing a precursor, whereby the precursor comprises a structure having a formula of Mx+F(x-δ)-yBy; and b) reacting the precursor with a fluorinating agent generating the amorphous metal flouride having a formula of Mx+Fx-δ, whereby M is selected from the group comprising metals of the second, third and fourth main group and any subgroup of the periodic table, B is a coordinately bound group; x is any integer of 2 or 3; y is any integer between 1 and 3; δ is 0 to 0.1; and x?δ>y.

Nitrogen trifluoride as an oxidative co-reagent in high temperature vapor phase hydrofluorinations

Nitrogen trifluoride (NF3) has proven to be a useful additive in high temperature vapor phase hydrofluorination reactions of chlorocarbons. The activity of chromium-based catalysts is maintained by introducing a co-stream of NF3 into the reagent chlorocarbon and HF stream. NF3 is a desirable additive instead of O2 as there is no water generation due to its use.

A selected ion flow tube study of the reactions of gas-phase cations with PSCl3

A selected ion flow tube was used to investigate the positive ion chemistry of thiophosphoryl chloride, PSCl3. Rate coefficients and ion product branching ratios have been determined at room temperature for reactions with 19 cations; H3O+, CF3+, CF +, NO+, NO2+, SF2 +, SF+, CF2+, O2 +, H2O+, N2O+, O +, CO2+, CO+, N+, N 2+, Ar+, F+ and Ne+ (in order of increasing recombination energy). Complementary data described in the previous paper have been obtained for this molecule via the observation of threshold photoelectron photoion coincidences. For ions whose recombination energies are in the range 10-22 eV, comparisons are made between the product ion branching rations of PSCl3 from photoionisation and from ion-molecule reactions. In most instances, the data from the two experiments are well correlated, suggesting that long-range charge transfer is the dominant mechanism for these ion-molecule reactions; the agreement is particularly good for the atomic ions Ar+, F+ and Ne+. Some reactions (e.g. O2++PSCl3), however, exhibit significant differences; short-range charge transfer must then be occurring following the formation of an ion-molecule complex. For ions whose recombination energies are less than 10 eV (i.e. H3O+, CF 3+, CF+ and NO+), reactions can only occur via a chemical process in which bonds are broken and formed, because the recombination energy of the cation is less than the ionisation energy of PSCl3.
