Abstract
Catalyst systems suitable for tetramerizing ethylene to form 1-octene may include a catalyst including a chromium compound coordinated with a ligand and a co-catalyst including an organoaluminum compound. The ligand may have a chemical structure according to Formula (1), wherein R1 is a (C3-C20) substituted or unsubstituted hydrocarbyl group; R2, R3, R4, and R5 are independently chosen from (C1-C50) hydrocarbyl groups; and R1 and N are in a cis configuration.
Claims20
A catalyst system suitable for tetramerizing ethylene to form 1-octene, the catalyst system comprising:
