Abstract

Det blir beskrevet en smørende sammensetning som omfatter en blanding av A) en hovedmengde med en olje av smørende viskositet, B) et dispergeringsmiddel i en effektiv mengde av minst et askefritt dispergeringsmiddel, og C) en mindre, effektiv mengde med minst et avemulgeringsmiddel kjennetegnet ved formelen. der R er en hydrokarbylgruppe, R, R, Roger hver uavhengig av hverandre H eller hydrokarbylgrupper, og X er 0 eller NR' der R' er hydrogen eller en hydrokarbylgruppe .I en utførelsesform er det askefrie dispergerings-middelet et karboksyl-dispergeringsmiddel, og avemul-geringsmiddelet er et derivat av imidazolin. De smørende sammensetningene fra oppfinnelsen er kjennetegnet ved at de har forbedret dlspergerbarhet, avemulgerbarhet, rust-hemming og antislitasje-egen-skaper.A lubricating composition is described which comprises a mixture of A) a major amount with an oil of lubricating viscosity, B) a dispersant in an effective amount of at least one ash-free dispersant, and C) a minor, effective amount having at least one demulsifier characterized by the formula. wherein R is a hydrocarbyl group, R, R, Roger are each independently H or hydrocarbyl groups, and X is O or NR 'where R' is hydrogen or a hydrocarbyl group. In one embodiment, the ash-free dispersant is a carboxyl dispersant, and the emulsifier is a derivative of imidazoline. The lubricating compositions of the invention are characterized in that they have improved dispersibility, de-emulsifiability, rust inhibition and anti-wear properties.
