Abstract

La presente invención se relaciona con un proceso para preparar un hidroclorofluorocarburo esencialmente libre de impurezas olefínicas mediante la hidrogenación selectiva de las impurezas olefínicas. El proceso puede ser controlado de modo que al menos una porción del hidroclorofluorocarburo sea convertida a fluorohidrocarburo.
