PURIFICATION OF SATURATED HALOCARBONS

摘要

A process for treating an impure mixture consisting essentially of at least one olefinic impurity and at least one saturated halocarbon selected from fluorocarbons and fluorohydrocarbons by contacting the mixture with a source of hydrogen in the presence of a hydrogenation catalyst, whereby the olefinic impurity is converted to a hydrogenated form thereof, to produce a treated mixture consisting essentially of the hydrogenated form of the olefinic impurity or impurities and the saturated halocarbon or halocarbons from the impure mixture.
