摘要： There is proposed a process for the purification of fluorinated lubricants, free from hydrogen, such as perfluorinated ethers or chlorofluorocarbons, whose elimination can be dangerous for the environment owing to the fluorine release, such a process consisting in dissolving the lubricant in a fluorochlorinated hydrocarbon, then in precipitating by means of a grease solvent, in separating, in degasing and finally in filtering in order to remove the mechanical impurities.
