Title: Perfluoroolefin and perfluoroparaffin mixture and process for making same

Patent ·
OSTI ID:6797564

Straight chain perfluoroolefins compounds of medium length with terminal or double bonds and a minor proportion of trifluoromethyl side chains or mixtures of such perfluoroolefins with perfluoro paraffins of equal chain length and corresponding structure, the perfluoroolefins being present in the mixture in an amount of 40 to 70% are prepared. The compounds are valuable as highly reactive intermediate products in the production of surface active agents. The compounds are made by subjecting a highly fluorinated organic compound to degradation by means of a high energy radiation of a density of 0.3 to 3.0 w/cm2 effected in a radiation chamber which has been subjected to a preceding rinsing with an inert gas or with a monomeric highly fluorinated organic compound.
