Abstract
EL FORMALDEHIDO Y/O METILAL SE HACE MEDIANTE LA ELECTROOXIDACION DE METANOL EN UN APARATO QUE SE DEFINE EN UN COMPARTIMENTO DE ANODO Y UN COMPARTIMENTO DE CATODO MEDIANTE UNA MEMBRANA CATIONICA HECHA DE UN FLUOROPOLIMERO QUE TENGA GRUPOS DE ACIDO SULFONICO O DE SULFONIL PENDIENTES, QUE ESTA RECUBIERTA SOBRE UNO DE SUS LADOS CON PLATINO APLICADO POR UN METODO DE IMPREGNACION/REDUCCION, DICHO RECUBRIMIENTO SIRVE COMO ANODO. EL CATODO PUEDE SER UNA CAPA DE METAL EN EL LADO OPUESTO DE LA MEMBRANA O UN CATODO DE METAL SEPARADO. CUANDO SE EMPLEA EL CATODO DE METAL SEPARADO, EL COMPARTIMENTO DEL CATODO CONTIENE UN ELECTROLITO LIQUIDO, QUE ES UN ACIDO ORGANICO CONCENTRADO, PREFERIBLEMENTE ACIDO FOSFORICO. CON PORCENTAJES DE TEMPERATURA ESPECIFICAMENTE IDENTIFICADOS, EL RENDIMIENTO DEL FORMALDEHIDO Y DEL METILAL PUEDE OPTIMIZARSE CONTROLANDO LA FRACCION DE MOL O LA PRESION PARCIAL DEL SUMINISTRO DE METANOL.
