Purification Methods
Reflux it for 24hours with saturated acid KMnO4 (to oxidise and remove hydrocarbons), then neutralise, steam distil, dry with P2O5 and pass slowly through a column of dry silica gel. [Glew & Reeves J Phys Chem 60 615 1956.] It can also be purified by percolation through a 1metre neutral activated alumina column, and 1H-impurities are checked by NMR.

Check Digit Verification of cas no
The CAS Registry Mumber 355-02-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 355-02:
(5*3)+(4*5)+(3*5)+(2*0)+(1*2)=52
52 % 10 = 2
So 355-02-2 is a valid CAS Registry Number.

THE VAPOUR PRESSURES AND EXCESS FREE ENERGIES OF MIXING OF THE SYSTEMS HEXAFLUOROBENZENE-CARBON TETRACHLORIDE AND HEXAFLUOROBENZENE-PERFLUOROMETHYLCYCLOHEXANE

, p. 267 - 278 (1980)
The vapour pressures of liquid mixtures of hexafluorobenezene with carbon tetrachloride and of hexafluorobenzene with perfluoromethylcyclohexane (tetradecafluoromethylcyclohexane) have been measured in the range of temperature 20-50 deg C, in a static system.These have been used to obtain the excess free energies of the mixtures.Both mixtures show large positive deviations from thermodynamic ideality, and also show azeotropic behaviour.

The fluorination of a wide range of polyfluorinated organic compounds with molecular fluorine in the gas phase in a layer of NiF2/support as catalyst was investigated.It was shown that the selectivity of fluorination of the series of fluoroolefins, acid fluorides, polyfluoroalkanes, and hydrogen-containing ethers can be greatly increased.The developed method was used on an industrial scale in the production of perfluorinated liquids.
