Abstract

Les compositions fluides lubrifiantes et fonctionnelles décrites comprennent au moins une huile de viscosité lubrifiante et une quantité à pression extrême et à modification de la friction de (A) au moins un ester de phosphite caractérisé par la formule (I), où R1 représente un groupe hydrocarbyle à chaîne droite et R2 représente un groupe hydrocarbyle à chaîne ramifiée. Sont également décrites des compositions qui comprennent la combinaison desdits esters de phosphite tels qu'ils sont représentés par la formule (I) et diverses compositions contenant du soufre. Les compositions comprenant ces combinaisons sont également utiles dans des compositions fluides lubrifiantes et fonctionnelles, telles que des huiles et des graisses lubrifiantes. Des systèmes aqueux contenant les esters de phosphite représentés par la formule (I) ainsi que des combinaisons d'ester de phosphite avec des compositions contenant du soufre sont également décrits.
