<p>A process for making base oil, comprising: oligomerizing one or more olefins having a boiling point less than 82°C in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40°C of 1100 mm2/s or higher. Also, a process, comprising: oligomerizmg the olefins in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40°C of 300 mm2/s or higher and a low cloud point, wherein a wt% y ield of products boiling at 482°C+ (900°F+) is at least 65 wt% of a total yield of products from the oligomerizing. Additionally, a process, comprising: oligomerizing the olefins in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40°C greater than 1100 mm2/s and a low cloud point.</p> |
