Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA DETERMINAR LA REACTIVIDAD QUIMICA, ESPECIALMENTE LA CORROSIVIDAD, DE UN LIQUIDO OLEOSO O DE LAS IMPUREZAS QUE SE CONTIENEN EN EL MISMO, CARACTERIZADO PORQUE SE UTILIZA UN TRANSISTOR DE EFECTO DE CAMPO (FET) CON UNA PUERTA ELECTRONICA SENSIBLE A LOS IONES, Y SE CREA UN POTENCIAL DE REFERENCIA POR MEDIO DE UN ELECTRODO DE REFERENCIA QUIMICAMENTE REACTIVO, PREFERENTEMENTE EL ALOJAMIENTO METALICO DEL RECIPIENTE DE ACEITE, Y LA DIFERENCIA DE POTENCIAL DERIVADA DE LAS REACCIONES DE REDUCCION - OXIDACION (REDOX) PUEDE DETECTARSE EN EL TRANSISTOR DE EFECTO DE CAMPO. EL PROCEDIMIENTO DE LA INVENCION NO UTILIZA NINGUN REACTIVO Y NO REFUERZA LAS REACCIONES QUIMICAS QUE OCURREN NATURALMENTE EN LA SUPERFICIE DEL METAL. POR CONSIGUIENTE, ES PARTICULARMENTE ADECUADO PARA MEDICION CONTINUA DE LA CORROSIVIDAD DE ACEITES MINERALES. PUEDE TAMBIEN DETERMINARSE EL CONTENIDO DE AGUA.
