    摘要: The present invention relates to a lubricant base oil containing an aromatic ester lubricant represented by the following Chemical Formula 1 and to a method for preparing the aromatic ester lubricant. By containing an aromatic ester lubricant, the lubricant base oil of the present invention exhibits an excellent dispersibility and fluidity and is ecofriendly due to a high biodegradability. In addition, the method for preparing the aromatic ester lubricant of the present invention 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.

    Wherein, the substituents R and Ar in the above Chemical Formula 1 are defined in the specification.
