Abstract

PROCESO MEJORADO PARA QUITAR RESIDUOS CATALITICOS BASADO EN EL A1C13 Y/O COMPUESTOS COMPLEJOS DE LO MISMO. SE DESCRIBE UN PROCESO SELECTIVO PARA QUITAR RESIDUOS CATALITICOS BASADOS EN A1C13 O SUS COMPUESTOS COMPLEJOS DERIVADOS DEL (CO)POLIMERISACION DE CORTES OLEFINICOS Y DIOLEFINICOS, PERMITIENDO LA PRODUCION DE RESINAS DE HIDROCARBONOS CASI INCOLORAS. ESTE PROCESO CONSISTE EN CONTACTAR LA MASA POLIMERIZADA CON UN COMPUESTO ORGANOMETALICO, TRATAR LAS MEZCLAS RESULTANTES CON AQUA O SOLUCIONES ACUACEOS, O BIEN ACIDOS O BIEN BASICOS, Y SEPARAR LA FASE ORGANICA, LA CUAL EN ESTE PUNTO ESTA SIN RESIDUOS INORGANICOS.
