Claims18
A fuel composition comprising:
- (i) a liquid fuel, and
- (ii) a compound of formula (I):
- wherein
- A, B, C and D represent, independently to each other, an alkyl or an alkenyl group with a number of carbon atoms resulting in a molar mass of A+B+C+D ranging from 84 to 10000 g/mol, wherein A is optionally hydrogen;
- each X represents independently to each other the monovalent radical of formula (II):
- wherein:
- each R1, R2, R3, identical or different, represent C1-C20 linear or branched, saturated or unsaturated, cyclic or acyclic, hydrocarbyl group;
- each Y represents a C1-C20 linear or branched, saturated or unsaturated, hydrocarbyl group optionally substituted by a functional group comprising oxygen and/or a nitrogen atom(s);
- each n represents an integer ranging from 1 to 20;
- and
- Z represents a C1-C16, linear or branched, saturated or unsaturated, cyclic or acyclic, hydrocarbyl group optionally substituted by a functional group comprising an oxygen and/or a nitrogen atom.

A method of using a compound of formula (I):
- wherein
- A, B, C and D represent, independently to each other, an alkyl or an alkenyl group with a number of carbon atoms resulting in a molar mass of A+B+C+D ranging from 84 to 10000 g/mol, being understood that A is optionally hydrogen;
- each X represents independently to each other the monovalent radical of formula (II):
- wherein:
- each R1, R2, R3, identical or different, represent C1-C20 linear or branched, saturated or unsaturated, cyclic or acyclic, hydrocarbyl group;
- each Y represents a C1-C20 linear or branched, saturated or unsaturated, hydrocarbyl group optionally substituted by a functional group comprising oxygen and/or a nitrogen atom(s);
- each n represents an integer ranging from 1 to 20;
- and
- Z represents a C1-C16, linear or branched, saturated or unsaturated, cyclic or acyclic, hydrocarbyl group optionally substituted by a functional group comprising an oxygen and/or a nitrogen atom;
- adding the compound as a detergent additive and/or as a demulsifying additive and/or as a lubricant additive and/or as a corrosion inhibitor additive and/or as an antioxidant additive and/or as a conductivity improver and/or as a metal deactivator, in a liquid fuel for an internal combustion engine.
