专利摘要

A lubricating oil composition comprises at least 50 percent by mass, based on the mass of the composition of an oil of lubricating viscosity and 0.01 to 25 percent by mass, based on the mass of the composition, of a compound having structure (I): wherein R1 and R2 are the same or different and are linear or branched alkyl groups having from 2 to 10, preferably from 2 to 8 carbon atoms. The compositions provide wear protection between sliding metal contacts, such as may be found in engines. ......

权利要求: 1. A lubricating oil composition comprising at least 50 percent by mass, based on the mass of the composition of an oil of lubricating viscosity and 0.01 to 25 percent by mass, based on the mass of the composition, of a compound having structure (I): wherein R1 and R2 are the same or different and are linear or branched alkyl groups having from 2 to 10, preferably from 2 to 8 carbon atoms.2. A lubricating oil composition according to claim 1 wherein R1 and R2 are the same or different and are linear alkyl groups.3. A lubricating oil composition according to claim 1 or claim 2 wherein at least one of R1 and R2 is n-propyl, n-butyl, n-hexyl or n-octyl.4. A lubricating oil composition according to any preceding claim wherein R1 and R2 are the same.5. A lubricating oil composition according to any preceding claim comprising one or more co-additives different from the compound having structure (I), the one or more co-additives being selected from dispersants, oxidation inhibitors or anti-oxidants, detergents, friction modifiers, and viscosity modifiers.6. A method of reducing friction and/or wear between contacting surfaces of a machine, the method comprising supplying a lubricating oil composition according to any preceding claims to the contacting surfaces.7. The use of a compound having structure (I): wherein R1 and R2 are the same or different and are linear or branched alkyl groups having from 2 to 10, preferably from 2 to 8 carbon atoms as an additive in a lubricating oil composition to reduce friction and/or wear between contacting surfaces of a machine lubricated by the composition, wherein the composition comprises least 50 percent by mass, based on the mass of the composition of an oil of lubricating viscosity and 0.01 to 25 percent by mass, based on the mass of the composition of the compound of structure (I).8. The method of claim 6 or the use of claim 7 wherein the machine having contacting surfaces lubricated by the composition is an internal combustion engine.
