Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA PRODUCCION DE DIMEROS DE (HEPO) EN DONDE EL HEPO SE DIMERIZA EN UN DISOLVENTE POLAR APROTICO EN PRESENCIA DE MEZCLAS DE CATALIZADORES CONSISTE EN UNA SAL METALICA DE ELEMENTOS DE LA PRIMERA SERIE DEL SISTEMA PERIODICO Y UNA AMINA TERCIARIA. A TRAVES DE LAS RELACIONES MOLARES DE SALES METALICAS A AMINAS TERCFIARIAS ENTRE 2/1 A 1/2 SE MEJORA LA SELECTIVIDAD PARA COMPUESTOS DIMERO, Y SE OBTIENE UN ELEVADO RENDIMIENTO DE LOS SIMEROS SIENDO HEPO OXIDO DE HEXAFLUOROPROPENO.
