Versuchsvorschrift

Tetrafluoroethylene pentamer (50 g) was added dropwise to the potassium salt of p-cresol (15 g) stirred in dry dimethyl formamide (100 ml) at 30° C. After addition of the pentamer, the reaction mixture was stirred for 45 minutes at 60° C. The cooled reaction mixture was poured into water. The oil which separated out was dissolved in ether, the ether layer washed with water, dried over magnesium sulphate, and distilled to give 40 g of the p-cresyl ether, C10F19OC6H4CH3, boiling point 110° C. to 114° C. at 10 mm Hg. Elementary analysis, infra-red spectra, mass spectrometry and nuclear magnetic resonance measurements confirmed the identity of the compound.
