Embodiment 1

[0059] A glass container with a volume of 50 mL and equipped with a stirrer was dried under vacuum and then purged with nitrogen. Add 5.0 mL of trichlorotri(tetrahydrofuran) chromium (III) (transition metal compound represented by formula (2)) in tetrahydrofuran with a concentration of 2.0 mmol / L and 5.0 mL (2-methoxyphenyl) 2 PN(methyl)P(2-methoxyphenyl) 2 (the compound represented by the formula (1)) was dissolved in tetrahydrofuran at a concentration of 2.0 mmol / L, and the resulting mixture was stirred at room temperature for 2 hours to obtain a reaction mixture. The solvent (tetrahydrofuran) contained in the reaction mixture was evaporated to dryness under reduced pressure to obtain a solid. 10 mL of toluene was added to the solid to form a suspension (a) having a chromium atomic concentration of 1.0 mmol / L.

[0060] An autoclave with a volume of 0.4 L and equipped with a stirrer and catalyst feeder was vacuum dried and then purged with argon. 80 mL of toluene was added...

Embodiment 2

[0080] A glass container with a volume of 50 mL and equipped with a stirrer was dried under vacuum and then purged with nitrogen. Add 0.7 mL of toluene, 2.0 mL of a solution of triisobutylaluminum (organoaluminum compound) in toluene with a concentration of 1.0 mol / L and 1.3 mL of methylaluminoxane manufactured by Tosoh-finechem under the trade name PMAO-S (Aluminoxane compound) A solution having an aluminum atomic concentration of 2.47 mol-Al / L in toluene, and the resulting mixture was stirred at room temperature for 10 minutes to prepare an aluminum-containing solution.

[0081] Another 50 mL glass container equipped with a stirrer was dried under vacuum and then purged with nitrogen. Add 5.0 mL of trichlorotris(tetrahydrofuran) chromium (III) (transition metal compound represented by formula (2)) in tetrahydrofuran with a concentration of 2.0 mmol / L and 5.0 mL (2-methoxyphenyl ) 2 PN(methyl)P(2-methoxyphenyl) 2 (the compound represented by the formula (1)) was dissolved ...

Embodiment 3

[0086] A glass container with a volume of 50 mL and equipped with a stirrer was dried under vacuum and then purged with nitrogen. Add 0.7 mL of toluene, 2.0 mL of tri-n-octylaluminum (organoaluminum compound) in toluene with a concentration of 1.0 mol / L and 1.3 mL of methylaluminoxane (PMAO-S) manufactured by Tosoh-finechem ( aluminoxane compound) in toluene with an aluminum atomic concentration of 2.47 mol-Al / L, and the resulting mixture was stirred at room temperature for 10 minutes to prepare an aluminum-containing solution.

[0087] Another 50 mL glass container equipped with a stirrer was dried under vacuum and then purged with nitrogen. Add 5.0 mL of trichlorotri(tetrahydrofuran) chromium (III) (transition metal compound represented by formula (2)) in tetrahydrofuran with a concentration of 2.0 mmol / L and 5.0 mL (2-methoxyphenyl) 2 PN(methyl)P(2-methoxyphenyl) 2 (the compound represented by the formula (1)) was dissolved in tetrahydrofuran at a concentration of 2.0 mmo...

Abstract

A process for producing an olefin oligomer, which comprises the steps of (1) contacting a transition metal compound with a compound represented by the formula, R1R2A-G-AR3R4, to produce a contact product (i), (2) contacting an alumoxane compound with an organoaluminum compound to produce a contact product (ii), and (3) contacting the contact product (i), the contact product (ii), and an olefin with one another, wherein A is a nitrogen atom, a phosphorus atom, an arsenic atom or an antimony atom; G is a divalent group; and R1, R2, R3 and R4 are independently of one another a hydrocarbyl group, a halogenated hydrocarbyl group, an oxygen-containing hydrocarbyl group, a sulfur-containing hydrocarbyl group, a selenium-containing hydrocarbyl group, or a tellurium-containing hydrocarbyl group.

Description

field of invention [0001] The present invention relates to a process for the production of olefin oligomers in high yield. Background of the invention [0002] WO 02 / 04119A1 discloses a process for the trimerization of olefins comprising contacting a monomeric olefin or mixture of olefins under trimerization conditions with a catalyst comprising (a) a source of chromium, molybdenum or tungsten, (b) a combination of at least Ligands of a phosphorus, arsenic or tellurium atom bonded to at least one hydrocarbyl or heterohydrocarbyl group with polar substituents, but excluding all cases where such polar substituents are phosphine, arsane or antimonyl groups, And optionally, (c) an activator. [0003] WO 2004 / 056477 A1 also discloses a process for trimerizing olefins comprising the steps of contacting an olefin feed stream with a catalyst system comprising a transition metal compound and a heteroatom ligand, and wherein the trimer is an olefin and Wherei...
