Abstract:
We provide a process to make a lubricant component, comprising: a. oligomerizing a feed comprising one or more olefins in an ionic liquid oligomerization zone, at oligomerization conditions, to form an oligomer; and b. alkylating the oligomer in the presence of an isoparaffin, in an ionic liquid alkylation zone, at alkylation conditions including a molar ratio of one or more olefins and one or more isoparaffins of at least 0.8, to form an alkylated oligomeric product that is a lubricant component having a kinematic viscosity at 100° C. of at least 6.9 mm2/s, a VI of at least 134, a cloud point less than or equal to −28° C., and a Bromine Number of less than or equal to 6.1.
