摘要:
A method for preparing a ketone group-containing estolide compound and a ketone group-containing estolide compound prepared thereby are disclosed. The method for preparing a ketone group-containing estolide compound includes converting biomass fat into a fatty acid; separating the fatty acid into a C16 saturated fatty acid and a C18 unsaturated fatty acid; increasing an amount of oleic acid through partial hydrogenation of the C18 unsaturated fatty acid; synthesizing a C35 ketone through ketonization of the oleic acid; and performing estolide bonding by capping the C16 saturated fatty acid onto the C35 ketone.

A method for preparing an estolide compound and an estolide compound prepared thereby are disclosed. The method for preparing an estolide compound includes: converting biomass fat into a fatty acid; separating the fatty acid into a C 16 saturated fatty acid and a C 18 unsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the C 18 unsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the C 16 saturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.

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.
