WIPO Patent Application WO/2023/051747
Kind Code:
A1
Abstract:
A lubricity improver and an application thereof. The lubricity improver comprises a compound having a structure shown in formula (I), groups R1 and R2 each independently being a single bond or a substituted or unsubstituted C1-C20 alkylene group, groups R3 and R4 each independently being hydrogen or a substituted or unsubstituted C1-C10 hydrocarbon group, groups X and Y each independently being hydrogen or a substituted or unsubstituted C1-C50 hydrocarbon group, and at least one of X and Y being hydrogen.
