Abstract
Official abstract text for this publication.
The present invention relates to a lubricant base oil containing an aromatic ester lubricant represented by Chemical Formula 1 and to a method for preparing the aromatic ester lubricant. By containing an aromatic ester lubricant, the lubricant base oil exhibits an excellent dispersibility and fluidity and is ecofriendly due to a high biodegradability. In addition, the method for preparing the aromatic ester lubricant does not generate such toxic substances as S, N, aromatic compounds and heavy metals and enables an easy control of the physical properties of a desired lubricant base oil by selecting a suitable alcohol compound to be introduced for an esterification reaction.
First claim
Opening claim text (preview).
What is claimed is: 1. A lubricant base oil comprising about 1 to about 40 wt % of an aromatic ester lubricant, the aromatic ester lubricant comprising a compound of chemical formula below, wherein the lubricant base oil has a pour point of about −40 to about −5° C., viscosity (at about 100° C.) of about 3.5 to about 6.5 cSt, and a cloud point of about −40 to about −5° C.:
