Abstract

PROCEDIMIENTO DE OBTENCION DE ACIDO GLIOXILICO POR ELECTROREDUCCION, CON REACTIVACION CATODICA, DE ACIDO OXALICO EN UNA CELDA ELECTROLITICA DIVIDIDA CONSTITUIDA POR UN COMPARTIMENTO ANODICO FORMADO POR UN ANODO Y UNA DISOLUCION ACUOSA DE UN ACIDO MINERAL FUERTE COMO ANOLITO Y POR UN COMPARTIMENTO CATODICO FORMADO POR UN CATODO DE PLOMO Y UNA DISOLUCION ACUOSA SATURADA DE ACIDO OXALICO, ESTANDO AMBOS COMPARTIMENTOS SEPARADOS POR UNA MEMBRANA DE INTERCAMBIO CATIONICO. EL PROCEDIMIENTO COMPRENDE ADICIONAR SALES DE PB (II) AL CATOLITO O AL ANOLITO PARA MANTENER ELEVADOS Y CONSTANTES A LO LARGO DEL TIEMPO DE OPERACION TANTO LA EFICACIA DE CORRIENTE COMO LA SELECTIVIDAD DEL PROCESO. EL EFECTO DE LAS SALES DE PB (II) PUEDE POTENCIARSE POR LAVADO DEL CATODO CON ACIDO NITRICO. EL ACIDO GLIOXILICO ES UN INTERMEDIO EN LA SINTESIS INDUSTRIAL DE LA P-HIDROXIFENILGLICINA Y LA VAINILLINA ENTRE OTROS PRODUCTOS.
