Thermal Decomposition of Some Perfluoro- and Polyfluorodiacyl Peroxides

Seven polyfluoroacyl peroxides were synthesized, some of them by a new procedure involving the direct interaction of an acyl fluoride with hydrogen peroxide.In the temperature range of 20-40 deg C, all these peroxides undergo first-order decomposition in dilute 1,1,2-trichloro-1,2,2-trifluoroethane (Freon-113) solutions (F-RF.Differing from other perfluoro or polyfluoro radicals, the perfluoro-α-isopropoxyethyl radicals (10) undergo substantial β scission to form perfluoroisopropyl radicals (11) during their lifetime.The ΔHexc. values for the perfluoroacyl peroxides are about 24 kcal mol-1, or about 5 kcal lower than that of the nonfluorinated diacyl peroxides (ca. 29 kcal mol-1).Apparently, the higher relative rates for 3 and 7 are caused by different factors.The latter peroxide (7) decomposes with a more favorable ΔSexc. term, whereas the former (3) decomposes with lower values of both ΔHexc. and ΔSexc..Thus, weakening of the peroxide bond by H bonding of the peroxide oxygen atom with the acidic ω-hydrogen atom seems to be implicated in the decomposition of 3.With a half-life of 81 min at 20 deg C, 3 may become a useful low-temperature initiator for free-radical reactions and polymerization.

SURFACE ACTIVE SUBSTANCES CONTAINING AN OLIGO(HEXAFLUOROPROPENE OXIDE) CHAIN AS A HYDROPHOBIC AND OLEOPHOBIC MOIETY

Oil soluble surface active substances, (HFPO)n-Ar, where Ar is an aryl group and (HFPO)n is an oligo(hexafluoropropene oxide) group, n = 2 - 5, were prepared and tested for their surface activities in toluene or m-xylene.Addition of a small amount of (HFPO)4-6-Ar (0.2 - 0.5 wtpercent) was found to decrease remarkably the surface tension of these solvents (down to 12 - 14 dyncm-1 at 20 deg C).Water soluble surfactans (HFPO)n-Ar'SO3Na, where Ar' is an arylene group, were also prepared by sulfonation of (HFPO)n-Ar.Some of these subtances (n = 4 - 6) decreased the surface tension of water down to 16 dyncm-1 at 20 deg C in the concentration of 10-4 - 10-5 molel-1.

Development of technology of perfluoroethyl isopropyl ketone production

Synthesis of perfluoroethyl isopropyl ketone by an interaction of hexafluoropropene with perfluoropropionic acid fluoride or hexafluoropropene oxide was examined. Interchangeability of perfluoropropionic acid fluoride and hexafluoropropene oxide was demonstrated. The features of perfluoroethyl isopropyl ketone synthesis were studied in polar aprotic solvents on catalysts: alkali metal fluoride. A method for obtaining perfluoroethyl isopropyl ketone by direct catalytic reaction in a tubular reactor without use of solvents was suggested and investigated. The mechanism of interaction was considered. The main impurities resulting in obtaining perfluoroethyl isopropyl ketone were determined. The methods of cleaning perfluoroethyl isopropyl ketone were worked out.

Catalytic synthesis of certain perfluorinated ketones and study of their structure by 19F NMR spectroscopy

An efficient catalyst of a perfluorinated ketone synthesis of a high selectivity in the absence of solvent was proposed. Products of reaction of perfluorinated fluorides of various structures with tetrafluoroethylene and hexafluoropropylene in the presence of efficient catalysts without solvent were examined. The structure of the resulting products and their isomeric composition were identified by 19F NMR spectrscopy. Pleiades Publishing, Ltd., 2013.
