ABSTRACT:
A method of removing olefinic impurity, such as perfluoroisobutylene, from fluoroperhalocarbon liquid, such as perfluorinated liquid, comprising the step of contacting the fluoroperhalocarbon liquid with a body of particles comprising particles selected from the group consisting of alumina, alkali metal oxide, alkali metal hydroxide, alkaline earth oxide, alkaline earth hydroxide, silicon oxide, tin oxide, zinc oxide, alkaline earth basic carbonate, and alkaline earth basic phosphate, transition metal oxide particles and mixtures thereof.
