Abstract

LA INVENCION SE REFIERE A UN PROCESO CONTINUO DE PREPARACION DE YODUROS DE PERFLUOROALKILO POR TELOMERIZACION TERMICA EN FASE GASEOSA DE TETRAFLUOROETILENO POR YODURO DE PENTAFLUOROETILO O DE HEPTAFLUOROISOPROPILO EN UN REACTOR TUBULAR. PARA MEJORAR LA SELECTIVIDAD EN UN TELOMERO DE RANGO DESEADO, SE RECICLAN LOS TELOMEROS DE RANGO INFERIOR EN AL MENOS UN PUNTO DEL REACTOR SITUADO ENTRE UNA VIGESIMA PARTE Y LAS TRES CUARTAS PARTES DE LA LONGITUD DEL TUBO.
