Abstract
METODO DE DESCOMPOSICION DE HIDROPEROXIDOS PRESENTES EN UN ACEITE LUBRICANTE, QUE COMPRENDE PONER EN CONTACTO EL ACEITE LUBRICANTE CON UN DESCOMPONEDOR DE HIDROPEROXIDO HETEROGENEO POR UN PERIODO DE TIEMPO SUFICIENTE PARA CAUSAR UNA REDUCCION EN LA CANTIDAD DE HIDROPEROXIDOS PRESENTES EN EL ACEITE, SIENDO EL DESCOMPONEDOR DE HIDROPEROXIDO INMOVILIZADO CUANDO SE CONTACTA CON EL ACEITE DEMANERA DE NO PASAR ADENTRO DEL ACEITE. EL DESCOMPONEDOR DE HIDROPEROXIDO ES MOS2, MO4S4 (RCOS2)6, NAOH, O MEZCLAS DE LOS MISMOS DONDE R ES UN GRUPO ALQUILO QUE TIENE DE 2 A 20 ATOMOS DE CARBONO.
