Abstract
Se trata de la inhibicion de la corrosion de metales en contacto con soluciones de alcanolaminas acuosas en unidades de eliminacion de gases ácidosmanteniendo en las soluciones de alcanolaminas cantidades efectivas inhibidoras de la corrosion de tiodialcanoles de formula S(ROH)2, donde R es alquilo(C1-10), arilo (C6-10), cicloalquilo (C3-10) o aralquilo (C7-12). El tiodialcanol es util para inhibir la corrosion de metales tanto en fracciones ricas comoen fracciones pobres de gases ácidos en unidades de eliminacion de dichos gases. también se proponen como objetos de la invencion dichos tiodialcanolesinhibidores y las soluciones que lo contienen.
