The present invention provides a process for producing a saturated aliphatic hydrocarbon prepared using an α-olefin as a raw material and represented by the general formula (1), including the steps of: (I) producing a vinylidene olefin by dimerizing the α-olefin in the presence of a metallocene complex catalyst; (II) further dimerizing the vinylidene olefin in the presence of an acid catalyst; and (III) hydrogenating the obtained dimer. Further, there are provided a lubricant composition containing the saturated aliphatic hydrocarbon compound produced by the above process, a bearing oil consisting of the lubricant composition, and making use of the same, a bearing and gyral equipment. The saturated aliphatic hydrocarbon compounds produced by the process of the present invention have low-temperature fluidity, exhibiting low evaporativity, and excellent in thermal stability and oxidation stability. Thus, the saturated aliphatic hydrocarbon compounds are suitable for use as, for example, a base oil of lubricant composition for hydraulic pressure, turbine, working machine, bearing, gear, metal-working, etc.
本发明提供了一种生产饱和脂肪族碳氢化合物的方法,该方法使用α-烯烃作为原料,并由一般公式(1)表示,其中包括以下步骤:(I)在金属茂络合物催化剂的存在下通过二聚化α-烯烃来生产乙烯基烯烃;(II)在酸催化剂的存在下进一步二聚化乙烯基烯烃;(III)对所得到的二聚体进行加氢。此外,还提供了一种润滑剂组合物,其中包含以上方法生产的饱和脂肪族碳氢化合物,一种由润滑剂组合物组成的轴承油,以及利用该油的轴承和陀螺设备。本发明所述的饱和脂肪族碳氢化合物具有低温流动性,表现出低蒸发性,并且在热稳定性和氧化稳定性方面表现优异。因此,该饱和脂肪族碳氢化合物适用于用作液压、涡轮、工作机、轴承、齿轮、金属加工等润滑剂组合物的基础油。
