Abstract: Catalyst compositions and processes for the oligomerization of ethylene to 1-octene are described. The catalyst composition includes a triamino bisphospino (NPNPN) ligand system with specific phosphorous and nitrogen ligands. The terminal nitrogen atoms include linear alkyl hydrocarbons that differ in the number of carbon atoms by 3.

Abstract: The disclosure provides a catalyst reaction mixture including a ligand having a backbone with at least one phosphorus atom and at least one nitrogen atom, a chromium compound, and a solvent mixture including decalin and at least one additional solvent, wherein the solvent mixture comprises decalin in an amount of less than 20 wt. % and, optionally, perhydroindane in an amount of 50 wt. % or less, based on the total weight of the solvent mixture. A method of forming a linear alpha olefin through ethylene oligomerization is also provided, the method including contacting ethylene gas with a reaction mixture in a reactor, the reaction mixture including the catalyst reaction mixture of the disclosure; and withdrawing a product stream including at least one linear alpha olefin, such as 1-butene, 1-hexene, or 1-octene, from the reactor.
