Abstract:
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.

Claim (Index 1):
A method for preparing an aromatic ester lubricant that is represented by Chemical Formula 1 below, the method comprising:\n converting biomass fat to fatty acids; separating C16-C19 saturated fatty acids and unsaturated fatty acids from the fatty acids; and esterifying the separated C16-C19 saturated fatty acids and unsaturated fatty acids with aromatic alcohol-based compounds. where in the above Chemical Formula 1, R represents a C15-C18 alkyl group or alkenyl group, and Ar represents a phenyl group, a phenyl group substituted with a C1-C4 alkyl or C6-C10 aryl, a naphthyl group, a naphthyl group substituted with a C1-C4 alkyl or C6-C10 aryl, an anthracene group, or an anthracene group substituted with a C1-C4 alkyl or C6-C10 aryl.
