Abstract
This invention relates generally to a improvement in a process for the purification of fluoroxy compounds, such as bis(fluoroxy)difluoromethane and fluoroxytrifluoromethane produced by the fluorination of carbon oxides. The improvement in effecting purification of the fluoroxy compounds is effected by initially selectively removing the fluorine by contacting with a crystalline zeolite and then removing the carbon oxide by selective adsorption.
