Abstract

METODO PARA RECUPERAR MOLIBDENO UNIDO ORGANICAMENTE, INSOLUBLE EN AGUA, DE RESIDUOS ORGANICOS DE CATALIZADOR AGOTADO DERIVADOS DE LA EPOXIDACION DE OLEFINAS. CONSTA DE LAS SIGUIENTES ETAPAS: 1. PONER EN CONTACTO EL RESIDUO DE CATALIZADOR AGOTADO CON UNA SOLUCION ACUOSA QUE CONTIENE UN AGENTE OXIDANTE DURANTE UN PERIODO SUFICIENTE PARA OXIDAR UNA PORCION DE DICHO MOLIBDENO A UNA FORMA SOLUBLE EN AGUA, DE MAYOR ESTADO DE OXIDACION Y PARA TRANSFERIR UNA PORCION DE DICHO MOLIBDENO A LA SOLUCION ACUOSA. 2. SEPARAR LA SOLUCION ACUOSA QUE CONTIENE EL MOLIBDENO. 3. AISLAR DICHO MOLIBDENO. EL AGENTE OXIDANTE SE ELIGE DE ENTRE EL PEROXIDO DE HIDROGENO, ACIDO NITRICO, HIPOCLORITO SODICO, PEROXIDO SODICO, CLORO Y OZONO. EL RESIDUO ORGANICO COMPRENDE EL RESIDUO SEMISOLIDO DERIVADO DE LA CONCENTRACION DE RESIDUOS DE CATALIZADOR PROCEDENTES DE LA EPOXIDACION DE OLEFINAS.
