“…Thanks to these physical properties, they have been used in numerous applications [1]. The chlorofluorocarbons (CFCs) are used as refrigerants, aerosol propellants, foaming agents, solvents and cleaning agents [1]. However, due to their effect on ozone depletion, a complete ban on their production by the year 2000 has been scheduled by the 1987 Montreal protocol and its latest amendments [2].…”

We have previously used two general solvation equations to correlate and to interpret a wide variety of physicochemical and biochemical properties of compounds (solutes). Application of these equations requires a knowledge of the relevant solute descriptors, viz. R 2 , the excess molar refraction, π 2 H , the solute dipolarity/polarizability, ∑α H 2 , ∑β 2 H , the solute overall hydrogen bond acidity and basicity, and logL 16 , where L 16 is the solute gas-hexadecane partition coefficient at 298 K. We have also shown that these solute descriptors can be obtained from partition coefficients of solutes in various water-solvent and gas-solvent systems. Here, we use this approach to calculate solute descriptors for a series of 18 organofluorocarbons, classed as refrigerants, including chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons and perfluorocarbons, using Henry's law coefficients in water and five organic solvents that we have already measured. These data have been used to calculate Ostwald solubility coefficients, log L. Gas-water and gas-solvent partitions have been then combined to give log P for partition between water and solvent. A number of log P and L values have also been taken from the Medchem97 database. There are enough data to obtain the above descriptors for the 18 organofluorocarbons, and then to estimate log P and L values in a large number of other solvents. The chemosensory properties of the organofluorocarbons are also estimated.

“…[1][2][3] Fluorinated organic compounds are also extensively used in the production of plastics, elastomers and membranes, owing to their specific thermal and chemical properties. 4,5 Perfluoro methyl vinyl ether (PMVE), CF 3 OCFQ Q QCF 2 (classified as hydrofluoroether HFE-216), can be used in the production of perfluoroalkoxy polymers (PFA), 4 as well as in plasma etching processes. 6,7 Evaporation and spills during the use of PMVE result in its release to the atmosphere.…”

Product formation in the reaction of perfluorinated methyl vinyl ether, CF 3 OCFQCF 2 , with OH radicals is studied theoretically using the M06-2X/aug-cc-pVTZ and CCSD(T) levels of theory. The stable endproducts in an oxidative atmosphere are predicted to be perfluorinated methyl formate, CF 3 OCFO, and fluorinated glycolaldehyde, CFOCF 2 OH, both with CF 2 O as coproduct. The prediction of glycolaldehyde as a product contrasts with experimental data, which found perfluoro glyoxal, CFOCFO, instead. The most likely explanation for this apparent disagreement is conversion of CFOCF 2 OH to CFOCFO, e.g. by multiple catalytic agents present in the reaction mixture, wall reactions, and/or photolysis. The formation routes for the glyoxal product proposed in earlier work appear unlikely, and are not supported by theoretical or related experimental work.
