Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA PREPARACION DE DISPERSIONES SOLIDAS DE SALES DE ACIDOS DE METALES TETRAVALENTES, QUE TIENEN ESTRUCTURA LAMINAR, Y SUS DERIVADOS SALINOS EN UNA MATRIZ DE SILICE, CONSISTIENDO DICHO PROCEDIMIENTO EN UNA DESLAMINACION DE LOS COMPUESTOS ANTES MENCIONADOS POR MEDIO DE UNA AMINA, HASTA OBTENER UNA DISPERSION COLOIDAL, EN LA OPERACION DE MEZCLAR DICHA DISPERSION COLOIDAL CON DISOLUCIONES ACUOSAS DE SILICE, EN LA GELIFICACION DE SILICE, POSIBLEMENTE EN EL PROCESO DE ELUIR LOS PRODUCTOS GELATINOSOS CON UN ACIDO MINERAL U ORGANICO, Y EN UN TRATAMIENTO CALORIFICO A UNA TEMPERATURA ENTRE 80 Y 650 (GRADOS) C. LAS DISPERSIONES SOLIDAS ASI OBTENIDAS TIENEN GRANDES AREAS SUPERFICIALES Y SE PUEDEN EMPLEAR COMO CAMBIADORES CATIONICOS; ADEMAS, SU ACIDEZ ES TAL QUE LAS HACE ADECUADAS COMO CATALIZADORES PARA REACCIONES CATALIZADAS POR ACIDOS.
