Abstract

PROCEDIMIENTO DE OBTENCION DE NUEVOS PERFLUOROALQUENOS Y SUS PRODUCTOS DE FLUORACION, QUE CONSISTE EN ISOMERIZAR LA OLEFINA (I) POR RADIACION CON LUZ ULTRAVIOLETA, GENERALMENTE A TEMPERATURA AMBIENTE, PARA OBTENER LOS NUEVOS PERFLUOROALQUENOS (IV) Y (V). ESTOS PRODUCTOS SE SOMETEN A UN PROCESO DE FLUORACION, POR PASO DE FLUOR GAS, GENERALMENTE A TEMPERATURA AMBIENTE, CON POSTERIOR RECTIFICACION, OBTENIENDOSE ASI LOS PERFLUOROALCANOS (VI) Y (IX). ESTOS PERFLUOROALCANOS, ALTAMENTE RAMIFICADOS, SON CAPACES DE PROPORCIONAR, A TEMPERATURAS SUPERIORES A 100GC, RADICALES DE PERFLUOROALQUILO QUE SE UTILIZAN COMO INICIADORES DE POLIMERIZACION DE MONOMEROS ETILENICAMENTE INSATURADOS, ESPECIALMENTE OLEFINAS FLUORADAS.
