Abstract

PROCEDIMIENTO PARA LA PREPARACION DE POLIFENILENOXIDO. CONSISTE EN: ALIMENTAR EN CONTINUO AL PIE DE UN REACTOR VERTICAL Y OBLONGO UN CATALIZADOR Y UN MONOMERO DISUELTOS EN UN DISOLVENTE LIQUIDO O MEZCLA DE DISOLVENTES LIQUIDOS INCAPACES DE DISOLVER EL POLIFENILENOXIDO; ALIMENTAR EN CONTINUO AL PIE DEL REACTOR UN FLUJO GASEOSO DE OXIGENO O GAS CONTENIENDO OXIGENO MOLECULAR; RECUPERAR DE LA PORCION DE CABEZA DEL REACTOR UNA DISPERSION DE POLIFENILENOXIDO SOLIDO EN LA CORRESPONDIENTE MEZCLA LIQUIDA DE REACCION; RECICLAR UNA PARTE DE LA DISPERSION Y ALIMENTARLA JUNTAMENTE CON EL CATALIZADOR Y EL 26-XILENOL EN LA CORRESPONDIENTE SOLUCION AL PIE DEL REACTOR MANTENIENDO UNA RELACION PONDERAL ENTRE PARTE RECICLADA Y ALIMENTACION FRESCA IGUAL A 100/1; RECUPERAR EL POLIFENILENOXIDO DE LA PARTE REMANENTE DE LA DISPERSION RECUPERADA DE LA PORCION DE CABEZA DEL REACTOR; Y CONTROLAR EL EFECTO TERMICO MEDIANTE INTERCAMBIO DE CALOR AL REACTOR.
