Abstract
Provided are a catalyst system for olefin oligomerization reaction and a method for olefin oligomerization, and more particularly, a catalyst system for olefin oligomerization reaction and a method for olefin oligomerization, which enable more efficient preparation of alpha-olefin, because a catalytic active ingredient is supported on a support, thereby exhibiting high activity in olefin oligomerization reaction even by using smaller amounts of a catalyst composition and a cocatalyst.
Claims14
A catalyst system for olefin oligomerization reaction, comprising a ligand compound comprising one or more diphosphine groups represented by the following Chemical Formula 1 in the molecule;
- a chromium source;
- and
- a support:
- wherein P is a phosphorus atom, and N is a nitrogen atom,
- R1 to R4 are the same as or different from each other, and each independently a hydrocarbyl group having 1 to 20 carbon atoms, a heterohydrocarbyl group having 1 to 20 carbon atoms, or a hydrocarboheteryl group having 1 to 20 carbon atoms, and
- * represents that the group of Chemical Formula 1 is a monovalent linkage group.
