Abstract

EL PRESENTE INVENTO SE REFIERE A UN PROCEDIMIENTO PARA PRODUCIR DICROMATO ALCALINO Y/O ACIDO CROMICO MEDIANTE ELECTROLISIS DE SOLUCIONES DE MONOCROMATO Y DICROMATO ALCALINO EN CELULAS ELECTROLITICAS. EL PROCEDIMIENTO SE CARACTERIZA PORQUE EL ANODO Y EL CATODO SE SEPARAN A TRAVES DE MEMBRANAS INTERCAMBIADORAS DE IONES; LA MEMBRANA INTERCAMBIADORA DE CATIONES ES UNA MEMBRANA DE UNA SOLA CAPA A BASE DE POLIMEROS PERFLUORADOS CON GRUPOS ACIDOS SULFONICOS Y EN EL ESPACIO ENTRE CATODOS SE PRODUCE UNA SOLUCION ACUOSA CON UN PH ENTRE 4 Y 14.
