| abstract |
More particularly, the present invention relates to a process for oligomerizing ethylene under a catalyst system comprising a transition metal or transition metal precursor, a ligand having a skeletal structure represented by the following formula (1), a cocatalyst, Hexene, and octene are recycled to oligomerize ethylene. Formula 1 R 1 -OYOR 2 or R 1 -OC (= O) -YC (= O) OR 2 Wherein R 1 and R 2 are independently hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl, or substituted heterohydrocarbyl, Y is a group linking O or C (= O) O, Substituted hydrocarbyl, heterohydrocarbyl, or substituted heterohydrocarbyl. The oligomerization method according to the present invention has a very large distribution of C10 " -C12 " alpha-olefins among the distribution of alpha-olefins produced, and has an excellent characteristic of alpha-olefin prepared. |
