Abstract
La presente invención se refiere a un procedimiento para tratar una mezcla impura que consiste esencialmente de por lo menos una impureza olefínica y por lo menos un halocarburo saturado que se selecciona de fluorocarburos y fluorhidrocarburos, el procedimiento está caracterizado porque se pone en contacto la mezcla con una fuente de hidrógeno, en presencia de un catalizador de hidrogenación, mediante lo cual la impureza olefínica se convierte en una forma hidrogenada de la misma, para producir una mezcla tratada que consiste esencialmente de la forma hidrogenada de una impureza o impurezas olefínicas y el halocarburo o halocarburos saturados a partir de la mezcla impura.
