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.
A catalyst reaction mixture comprising a ligand having a backbone with at least one phosphorus atom and at least one nitrogen atom, wherein the ligand has the structure (R1)(R2)N—P(R3)—N(R4)—P(R5)—N(R6)(R7), wherein R1, R2, R3, R4, R5, R6, and R7 are each independently hydrogen, optionally substituted amino, trialkylsilyl, or optionally substituted C1-C20 hydrocarbyl, a chromium compound, and a solvent mixture comprising decalin and at least one additional solvent, wherein the solvent mixture comprises decalin in an amount of about 5 to 20 wt. % and contains perhydroindane in an amount of 50 wt. % or less, based on the total weight of the solvent mixture.
The method of 11, wherein the product stream comprises a polymer content of about 0.9 wt. % or less, based on the total weight of the product stream.
