Claims22
A composition comprising at least 50 mole % C20 2-substituted alpha olefins, wherein the C20 2-substituted alpha olefins comprise 2-(3-methylheptyl)-7-methyl-1-undecene, 2-(4-octyl)-7-methyl-1-undecene, 2-(3-methylheptyl)-5-propyl-1-nonene, 2-(2-ethylhexyl)-7-methyl-1-undecene, 2-(3-methylheptyl)-6-ethyl-1-decene, or any combination thereof.
A process comprising:
- 1) contacting i) a C10 olefin composition comprising branched C10 olefins, the branched C10 olefins comprising 3-propyl-1-heptene, 4-ethyl-1-octene, 5-methyl-1-nonene or any combination thereof, and ii) a dimerization catalyst or dimerization catalyst system;
- 2) forming a reaction product comprising at least 50 mole % C20 2-substituted alpha olefins;
- and 3) isolating a composition comprising at least 50 mole % C20 2-substituted alpha olefins, wherein the C20 2-substituted alpha olefins comprise 2-(3-methylheptyl)-7-methyl-1-undecene, 2-(4-octyl)-7-methyl-1-undecene, 2-(3-methylheptyl)-5-propyl-1-nonene, 2-(2-ethylhexyl)-7-methyl-1-undecene, 2-(3-methylheptyl)-6-ethyl-1-decene, or any combination thereof.
