Abstract

LA INVENCION SE REFIERE A INHIBIDORES DE LA CORROSION ORGANICA PARA UTILIZACION EN COMPOSICIONES REFRIGERANTES ANTICONGELANTES. DICHOS INHIBIDORES COMPRENDEN UN COMPONENTE DE ACIDO MONO CARBOXILICO C 8 O ISOMEROS O SALES DEL MISMO, Y UN ACIDO NEO - DECANOICO O ISOMEROS O SALES DEL MISMO. LOS INHIBIDORES DE LA PRESENTE INVENCION PROPORCIONAN A LAS SUPERFICIES METALICAS UNA PROTECCION MEJORADA FRENTE A LA CORROSION, COMPARADOS CON LOS INHIBIDORES CONVENCIONALES Y PROPORCIONAN UNA PROTECCION FRENTE A LA CORROSION SORPRENDENTEMENTE MEJORADA, COMPARADOS CON LOS INHIBIDORES QUE CONTIENEN SOLO UN UNICO COMPONENTE DE ACIDO MONO - CARBOXILICO.
