(EN) LUBRICATING OIL HAVING IMPROVED RUST INHIBITION AND DEMULSIBILITY
(FR) HUILE LUBRIFIANTE PRESENTANT UNE INHIBITION DE LA ROUILLE ET UNE DESEMULSIBILITE AMELIOREES
Abrégé
(EN) The rust inhibiting and demulsibility performance of a lubricating oil can be synergistically enhanced by incorporating a rust inhibitor having at least one COOH acid group and a particular class of pyridine derivatives.
(FR) On peut améliorer de manière synergique les qualités d'inhibition de la rouille et de désémulsibilité d'une huile lubrifiante en incorporant un inhibiteur de rouille possédant au moins un groupe acide COOH et une classe particulière de dérivés de la pyridine.
