Abstract
PROCEDIMIENTO PARA LA PREPARACION DE UN CATALIZADOR A BASE DE OXIDOS DE MOLIBDENO Y DE HIERRO. SE PRECIPITA EN UN MEDIO ACUOSO, UN COMPUESTO SOLUBLE DE MOLIBDENO Y UNA SAL FERRICA SOLUBLE. SE SEPARA EL PRECIPITADO DE SUS AGUAS MADRES Y SE LAVA CON AGUA DESIONIZADA. LAS AGUAS MADRES Y/O LAS LAVAZAS DEL PRECIPITADO SE PONEN EN CONTACTO CON UNA RESINA DE INTERCAMBIO ANIONICO DEBIL SALIFICADA CON ACIDO, CON EL FIN DE BLOQUEAR EN LA RESINA IONES MOLIBDICOS PRESENTES. DICHOS IONES SE RECUPERAN EN FORMA DE MOLBDATO DE METAL ALCALINO, NORMALMENTE HIDROXIDO SODICO. SE UTILIZA EN FORMA DE UN LECHO FIJO EN LOS PROCEDIMIENTOS DE OXIDACION DE NETANOL A FORMALDEHIDO.
