Abstract: Phenols react with tetrafluoroethylene at normal or reduced pressure when using about 0.05 to about 0.5 mole of an alkali metal hydroxide per each equivalent of phenolic hydroxy group as a catalyst and a water-miscible polar inert solvent to yield aryl-1,1,2,2-tetrafluoroethyl ethers. The products are useful as intermediates in the synthesis of dyestuffs and plant-protecting agents.

Abstract: Tetrafluoro-ethylene can be added to monoamines having oxyethyl or oxypropyl groups in aprotic polar solvents in the presence of alkali metals. The new monoamines obtained having the radicals tetrafluoro-ethyloxy-ethyl or tetrafluoro-ethyl-oxy-propyl are electrolyzed in anhydrous hydrofluoric acid, thus forming new monoamines in which all or nearly all hydrogen atoms of the starting compounds are replaced by fluorine.

Abstract: A method for improving the activity of a used supported silver catalyst, used for the manufacture of ethylene oxide by reaction of ethylene with oxygen or air, which method consists essentially of: (a) impregnating said used catalyst at a temperature from 80 DEG C. to 150 DEG C. and for 0.75 hour to 10 hours with an impregnating solution containing water, a water-miscible organic solvent selected from the group consisting of methanol, ethanol, propanol, and isopropanol, at least one compound of cesium, rubidium, or of cesium and rubidium in an amount providing from 50 mg to 1000 mg per kilogram of solution, said solution containing from 5 to 50 percent by weight of water; (b) separating the impregnated catalyst from excess impregnating solution; and (c) drying the impregnated catalyst.
