Abstract
The present invention relates to a catalyst system for olefin oligomerization and a method for olefin oligomerization, and more specifically, a catalyst system for olefin oligomerization and a method for olefin oligomerization that have more improved supporting efficiency due to a ligand compound capable of functioning as a tether to a support, and thus, exhibit high activity in the olefin oligomerization even with smaller amounts of catalyst composition and cocatalyst, thus enabling more efficient preparation of alpha-olefins.
Claims13
A catalyst system for olefin oligomerization comprising
- a ligand compound comprising two or more diphosphino moieties represented by the following Chemical Formula 1 in the molecule, and comprising a linker(L) connecting each moiety represented by the Chemical Formula 1:
- a chromium source;
- and
- a support where the ligand compound is supported.
- in the Chemical Formula 1,
- P is a phosphorous atom,
- A is nitrogen(N), arsenic(As), or antimony(Sb),
- R1 to R4 are identical or different, and each independently, a C1-20 hydrocarbyl group, heterohydrocarbyl group, or hydrocarboheteryl group,
- is a part that binds with the linker(L) connecting two or more moieties.
