Abstract
Oligomer products are produced by reacting an alpha olefin and a vinylidene compound in the presence of a solid catalyst, such as a solid oxide or a chemically-treated solid oxide. Metallocene compounds, organoaluminum compounds, and BF3 are not needed to perform the reaction. Oligomer products formed by processes disclosed herein have a trimer:tetramer weight ratio of at least 2:1.
Claims35
A process comprising:
- (i) contacting an alpha olefin, a vinylidene, and a solid catalyst in a reaction zone, wherein the solid catalyst comprises a solid oxide and/or a chemically-treated solid oxide and the reaction zone is substantially free of BF3, metallocene compounds, and organoaluminum compounds;
- and
- (ii) forming an oligomer product in the reaction zone having a trimer:tetramer weight ratio of at least 2:1.
A process comprising:
- (i) contacting an alpha olefin, a vinylidene, and a solid catalyst in a reaction zone, wherein the solid catalyst comprises a solid oxide and/or a chemically-treated solid oxide and the vinylidene comprises a dimer of 1-butene, a dimer of 1-pentene, a dimer of 1-hexene, a dimer of 1-octene, a dimer of 1-decene, a dimer of 1-dodecene, a dimer of 1-tetradecene, a dimer of 1-hexadecene, or any combination thereof;
- and
- (ii) forming an oligomer product in the reaction zone having a trimer:tetramer weight ratio of at least 2:1.
A process comprising:
- (i) contacting an alpha olefin, a vinylidene, and a solid catalyst in a reaction zone, wherein the solid catalyst comprises a solid oxide and/or a chemically-treated solid oxide and an amount of the solid catalyst in the reaction zone is in a range from 2 wt. % to 20 wt. %, based on a total amount of the alpha olefin and the vinylidene;
- and
- (ii) forming an oligomer product in the reaction zone having a trimer:tetramer weight ratio of at least 2:1.
