Abstract

PROCEDIMIENTO PARA PREPARAR ACIDO GLIOXILICO. CONSISTE EN OXIDAR ANODICA Y ELECTROQUIMICAMENTE A UNA SOLUCION ACUOSA DE GLIOXAL, EN UN ELECTROLIZADOR Y A UNA TEMPERATURA ENTRE 0 Y 70JC, PARA OBTENER UN ACIDO GLIOXILICO. EL ELECTROLIZADOR COMPRENDE: UN COMPARTIMENTO CATODICO QUE TIENE UN CATODO DE MATERIAL CONDUCTOR DE ELECTRICIDAD ESTABLE QUIMICA Y ELECTROQUIMICAMENTE COMO PLATINO O ACERO INOXIDABLE Y UN CATOLITO COMO UNA SOLUCION ACUOSA DE HIDROXIDO DE METAL ALCALINO; UN COMPARTIMENTO ANODICO QUE TIENE UN ANODO COMO PLATINO O CARBONO VITREO Y UN ANOLITO COMO AGUA, GLIXAL, ADITIVOS COMO SN O AG Y UN ELECTROLITO DE UN PRODUCTO MUY SOLUBLE EN AGUA QUE CONTIENE UN ANION ELEGIDO ENTRE ANIONES CLORURO, NITRATO Y SULFATO Y UN SEPARADOR DE VIDRIO SINTERIZADO.
