Abstract
Perfluorinated 1,2-epoxides are made by reacting a perfluorinated olefin with oxygen difluoride. Suitable olefins are those containing 2-14 carbon atoms and one or more olefinic double bonds, e.g. perfluoroalkenes, perfluorocycloalkenes, perfluorocycloalkylalkenes and perfluoroarylalkenes. The reaction may be effected in the vapour phase or in the liquid phase, optionally in the presence of gaseous or liquid diluents and/or a fluorination catalyst, e.g. silver difluoride. The preferred temperature range is - 50 DEG to 200 DEG C. The perfluorinated alkane corresponding to the olefin is obtained as a side product. Examples relate to 1,2-epoxy-perfluoropropane and 1,2-epoxy - perfluoroisobutane.
