Title: PROCESS FOR PURIFYING CRUDE PERFLUOROCARBONS

Abstract

A method is described for refining organic perfluoro compounds. In the manufacture of perfluorinated compounds by the fluorination of hydrocarbons, the product frequently is contaminated ny incompletely fluorimated hydrogen containing impurities. These impurities can be removed by contacting the products in a fluid conditions with an active adsorbents such as silica gel or alumina gel. The patent claims are restricted to this refining of crude perfluorinated lubricating oil.
