Abstract:
1. A lubricant composition, comprising: (a) a saturated aliphatic hydrocarbon compound represented by formula (1): where R (b) a saturated aliphatic hydrocarbon compound represented by formula (2): where R wherein the saturated aliphatic hydrocarbon compound contains 11-methyl-11,13-dioctyl tricosane in an amount of 55% by mass or more, wherein the saturated aliphatic hydrocarbon compound contains 92.5% or more by mass of hydrocarbon with 40 carbon atoms, and wherein the content of 11-methyl-11,13 dioctyl tricosane occupied in the hydrocarbon product with 40 carbon atoms is 75% or more by mass; wherein said saturated aliphatic hydrocarbon compound of formula (1) is prepared using an α-olefin as a raw material by a process comprising: (I) producing a vinylidene olefin by dimerizing the α-olefin in a presence of a metallocene complex catalyst; (II) further dimerizing the vinylidene olefin in a presence of an acid catalyst; and (III) hydrogenating a dimer obtained by the step (II); and (c) at least one member selected from an antioxidant, an oiliness agent, an extreme pressure agent, a detergent-dispersant, a viscosity index improver, a rust preventing agent, a metal deactivator, and an defoaming agent.
