The synthesis of perfluoroamine using nitrogen trifluoride

The reactions of nitrogen trifluoride (1) with hexafluoropropene (2) in the presence of cesium fluoride (CsF) gave 2- (3) and 1-heptafluoropropyldifluoroamine (4) in moderate yields. Tetrafluoroethylene (6) and octafluoro-2-butene (8) similarly reacted with 1 to give corresponding products.

Synthesis of perfluoroalkanes in high-temperature fluorination of graphite with fluorine in a reactor with a free-falling graphite bed

Reaction between fluorine and graphite in a reactor with a free-falling bed of graphite was studied in relation to the temperature in the reaction zone, ratio of the feeding rates of fluorine and graphite, and dilution of fluorine with an inert gas. Pleiades Publishing, Inc., 2006.

GAS PHASE RADIATION CHEMISTRY OF HEXAFLUOROETHANE

The Co-60 gamma radiolysis of gaseous C2F6 was investigated at 50 Torr pressure, both pure and with 10percent oxygen added.For the pure system, the radiolytic products and their respective G values were CF4, 2.27; C3F8, 0.23; C4F10, 0.09; C5F12, 0.015; and C6F14, 0.009.All radiolysis products except for CF4 (C = 0.61) were eliminated when 10percent O2 was added as scavenger.The results are discussed mainly in terms of the decomposition of excited C2F6 into free radicals, which can then combine.The unscavenged CF4 is accounted for by the ion-molecule reaction CF3+ + C2F6 -> CF4 + C2F5+.

Reaction of Pentafluoroethyl Radicals with Cyanogen Chloride

The reaction of C2F5 radicals with cyanogen chloride was studied between 293 and 573 K, using perfluoroethyl iodide as the free-radical source. The main product, C2F5Cl is formed via an addition reaction or by abstraction of a chlorine atom by C2F5.The reactions involved are C2F5+ClCN->C2F5Cl+CN (2) C2F5+ClCN->/C2F5Cl+CN (4) C2F5+C2F5->C4F10 The Arrhenius plot shows pronounced curvature.The following rate constants were obtained for reactions (2) and (4) where kc is the rate constant for C2F5 combination. The results are compared with those for the reaction of CF3 with ClCN.

Decomposition characteristics of C5F10O/air mixture as substitutes for SF6 to reduce global warming

Sulfur hexafluoride (SF6) is widely used in the power industry but is a serious greenhouse gas. Many researchers committed to achieving sustainable development of the power industry are finding alternatives to SF6 gas. C5F10O performs well in terms of environmental protection, insulation, and safety and is a potential environment-friendly alternative gas. In this paper, the insulation and decomposition characteristics of C5F10O/air gas mixture were examined using gas-insulation performance test platform, and decomposition products were detected by gas chromatography–mass spectrometry. The formation mechanism and distribution of C5F10O decomposition products were analyzed through reactive molecular dynamics method and density functional theory. The influence of air on the decomposition of C5F10O was also evaluated. Results showed that the decomposition of C5F10O/air gas mixture mainly produces CF3[rad], C3F7[rad], C4F7O[rad], CO, CF2[rad], CF[rad], F[rad] and CF4. The breakdown voltage of C5F10O/air gas mixture decreased slightly after repeated breakdown tests, and CF4, C2F6, C3F8, C3F6, C4F10, CF2O were detected. These results can serve as a reference for the systematic comprehension of the decomposition characteristics of C5F10O/air gas mixture and for related engineering applications.

Investigation of CF2 carbene on the surface of activated charcoal in the synthesis of trifluoroiodomethane via vapor-phase catalytic reaction

This paper investigates the synthetic mechanism of trifluoroiodomethane (CF3I) in the reaction of trifluoromethane and iodine via vapor-phase catalytic reaction. It is suggested that CF2 carbene is the key intermediate and is formed in the pyrolysis process of CHF3 at high temperature. However, in pyrolysis of CHF3 under activated charcoal (AC) existing conditions, no C2F4 was detected. H2 and 2-methyl-2-butene could not trap the CF2 carbene. When treating the remained compounds on the used AC with H2, CH4 is formed on the process. It is proposed that CF2 carbene combines with AC strongly and transfers into CF3 radical on heat. In addition, it is found that the AC is not only the catalyst supporter to form CF3I, but also a co-catalyst to promote the formation of CF2 carbene and CF3 radical.

Carbon-chain isomerization during the electrochemical fluorination in anhydrous hydrogen fluoride - A mechanistic study

The compounds i-C4H9SO2F, i-C3H7SO2F and cyclo-C3 H7C(O)F have been subjected to electrochemical fluorination in anhydrous hydrogen fluoride. The resulting products were fully analyzed by NMR spectroscopy. From the reaction balances, literature data and quantum chemical calculations, a new mechanism for carbon-chain isomerization during the electrochemical fluorination (ECF) is proposed. The key step in the formation of isomeric products is believed to be a ring closure reaction involving carbo-cationic or biradical intermediates.
