Abstract
Disclosed herein are embodiments of a process which generally includes contacting i) a monomer or mixture of monomers, ii) a haloaluminate ionic liquid, and iii) one or more halide components in a reaction zone, and oligomerizing the monomer or mixture of monomers in the reaction zone to form an oligomer product. The combination of the haloaluminate ionic liquid and halide component can constitute a catalyst system which is used in embodiments of the process to produce the oligomer product.

A process comprising;
- contacting i) a monomer comprising a C6 to C20 olefin, ii) a haloaluminate ionic liquid, and iii) a halide component comprising a C1 to C12organohalide in a reaction zone;
- and
- oligomerizing the monomer in the reaction zone to form an oligomer product;
- wherein the oligomer product has an average molecular weight from 400 to 611 grams/mol,
- wherein the oligomer product is formed in a presence of less than 8 mol % isoparaffin based upon moles of monomer in the reaction zone,
- wherein a molar ratio of a halide in the halide component to an aluminum in the haloaluminate ionic liquid is at least 0.14:1, and
- wherein the oligomer product is formed at a temperature from 15° C. to 125° C.
The process of claim wherein the oligomer product is formed in the presence of less than 6 mol % isoparaffin based upon the moles of monomer in the reaction zone.
