Abstract
The present patent application relates to the use, as detergent additive in a lubricating composition intended for a motorization system, of a spiro compound of formula (I) in which M is an atom selected from boron and aluminum; R, independently of one another, represent a hydrocarbon group comprising from 1 to 50 carbon atoms; and n1 and n2, independently of one another, equal 0, 1 or 2. It also relates to a lubricating composition intended for the lubrication of a motorization system, comprising one or more base oils and at least one spiro compound of formula (I), and to a process for lubricating a motorization system using such a composition.
Claims18
A method comprising adding at least one spiro compound to a lubricant comprising at least one base oil, the spiro compound(s) being represented by formula (I):
- wherein:
- M is chosen from boron or aluminum;
- n1 and n2 are independently selected from 0, 1, or 2;
- and
- each R independently represents a hydrocarbon group comprising from 1 to 50 carbon atoms.
A lubricant for a motor, the lubricant comprising:
- at least one base oil;
- and
- at least one spiro compound represented by formula (I):
- wherein:
- M is chosen from boron or aluminum;
- n1 and n2 are independently selected from 0, 1, or 2;
- and
- each R group is independently selected from a hydrocarbon group comprising from 1 to 50 carbon atoms.
