Abstract
La presente invención se refiere a un procedimiento para reducir el contenido de impurezas insaturadas en fluorohalocarburos, fluorohalohidrocarburos saturados y mezclas de los mismos, el procedimiento está caracterizado porque comprende poner en contacto los fluorohalocarburos y/o flurohalohidrocarburos que tienen una o más impurezas insaturadas en un estado fluido sustancialmente seco, con una composición de óxido metálico sólido amorfo, sustancialmente seco que consiste esencialmente de óxido cúprico, óxido de plata, óxido de cobalto III, dióxido de maganeso, o una mezcla de cualquiera de dos o más de los óxidos metálicos, a una temperatura efectiva, y recuperar los fluorohalocarburos y/o fluorohalo-hidrocarburos saturados que tienen un contenido reducido de impureza insaturada.
