Beschreibung
Zusammenfassung:	A phosphorous- and sulfur-containing additive and its use to impart anti-wear properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmission fluids, is disclosed. The additive comprises a mixture of products formed, for example, by simultaneously reacting (1) a beta-hydroxy thioether, such as thiobisethanol, (2) a phosphorous-containing reactant, such as triethyl phosphite and (3) optionally, a nucleophilic reactant capable of reacting with the episulfonium cation having general formula (I) to form thioether species. L'invention concerne un additif contenant du phosphore et du soufre ainsi que son utilisation conférant des propriétés anti-usure à des compositions huileuses telles que des carburants et des huiles lubrifiantes, notamment des compositions pour boîtes de vitesses, telles que des fluides pour transmission automatique. Ledit additif comprend un mélange de produits formé, par exemple, par réaction simultanée (1) d'un bêta-hydroxy thioéther tel qu'un thiobiséthanol, (2) d'un réactif contenant du phosphore tel que du triéthyle phosphite et (3) facultativement d'un réactif nucléophile capable de réagir avec le cation d'épisulfonium de formule (I), pour former des espèces de thioéther.
