LUBRICANT BASE OIL AND METHOD FOR PRODUCING SAME |
| 摘要 |
A lubricant base oil that is a hydrocarbon oil having a kinematic viscosity at 100° C. of 2.0 to 9 mm2/s, a viscosity index of 130 or more, a freezing point of −30 to −5° C., and an SBV viscosity at −20° C. of 1,000 to 60,000 mPa·s, in which the freezing point of the lubricant base oil is higher by 10° C. or more than a freezing point of raffinate obtained by bringing the lubricant base oil into contact with urea and removing paraffin that can be included in the urea. |

1. A lubricant base oil that is a hydrocarbon oil having a kinematic viscosity at 100° C. of 2.0 to 9 mm2/s, a viscosity index of 130 or more, a freezing point of −30 to −5° C., and an SBV viscosity at −20° C. of 1,000 to 60,000 mPa·s, wherein
the freezing point of the lubricant base oil is higher by 10° C. or more than a freezing point of raffinate obtained by bringing the lubricant base oil into contact with urea and removing paraffin that can be included in the urea. |
