Title:
ESTER COMPOUND AND PREPARATION METHOD THEREFOR AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/078249
Kind Code:
A1
Abstract:
The present invention provides an ester compound capable of being used as a lubricant additive or a lubricant base oil, and a preparation method therefor and uses thereof. The ester compound of the present invention has excellent viscosity-temperature properties and low-temperature properties, and can be used as a lubricant base oil. In addition, the ester compound of the present invention as a viscosity index improver has excellent viscosity-temperature properties and low-temperature properties, as an anti-wear agent can remarkably reduce the wear scar diameter of the base oil, and as a friction improver can remarkably reduce the friction coefficient of the base oil, thus exhibiting excellent anti-wear and anti-friction properties.
