Provided are a method of producing a Lube base oil composition including a) reacting at least a part of waste plastic pyrolysis oil having a boiling point in a range of 180 to 340° C. to remove impurities and oligomerize the oil; and b) hydroisomerizing at least a part of the product of step a). A lube base oil composition is also produced therefrom.

Method of producing lube base oil from middle distillate in pyrolysis oil derived from waste plastic

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 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

Provided are an optical film using a cellulose derivative, useful in an image display device, such as a liquid crystal display or the like, a retardation film and a polarization film using the optical film, and a liquid crystal display having excellent view angle characteristics by using these films, while the optical film uses a cellulose derivative resin in which some hydrogen atoms of hydroxy groups of cellulose are substituted with three or more kinds of substituents.
