Proposed is a mineral lubricating base oil having improved low-temperature performance, in which the lubricating base oil has kinematic viscosity of 9.0 cSt or less (at 40&#xb0; C.), kinematic viscosity of 2.5 cSt or less (at 100&#xb0; C.), and a pour point of &#x2212;50&#xb0; C. or less.

Mineral base oil having improved low temperature property, method for manufacturing same, and lubrication oil product comprising same

Disclosed is a mineral base oil including 85 to 92 wt % of a paraffinic hydrocarbon and 8 to 15 wt % of a naphthenic hydrocarbon and having a Noack volatility of 10 to 12 wt % and a viscosity index of 132 to 142.

Mineral base oil having high viscosity index and improved volatility and method of manufacturing same

Disclosed is a method of producing a lubricating base oil, including providing a feedstock including a diesel fraction, subjecting the feedstock to catalytic dewaxing, and recovering a lubricating base oil from a product of the catalytic dewaxing. A lubricating base oil produced thereby and a lubricant product including the lubricating base oil are also provided.

Method of producing lubricating base oil from feedstock comprising diesel fraction, and lubricating base oil produced thereby

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 Csaturated fatty acid and a Cunsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the Cunsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the Csaturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.

Estolide compound and method for preparing the same

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.
