摘要:
The present invention relates to a ligand compound, a catalyst system for olefin oligomerization, and a method for oligomerizing olefins using the same. The ligand compound according to the present invention has a structure in which a substituent is substituted in the trans form, and thereby when used for olefin oligomerization, the activity of the catalyst used and the selectivity of 1-hexene and 1-octene can be increased.
摘要:
The process includes reacting a reaction mixture comprising magnesium ethoxide (Mg(OEt)2), triethylaluminum (TEAl), and 2-ethylhexanol (2-EHOH) to form magnesium 2-ethyl hexyl alkoxide (Mg(2-EHO)2) and contacting Mg(2-EHO)2 in hexane with a first agent to form a reaction product “A.” The process further includes contacting the reaction product “A” with a second agent to form a reaction product “B”, wherein the second agent includes a transition metal and a halogen. The process further includes contacting the reaction product “B” with a third agent to form a reaction product “C”, wherein the third agent includes a first metal halide. In addition, the process includes contacting the reaction product “C” with a fourth agent to form a reaction product “D”, wherein the fourth agent includes a second metal halide. The process also includes contacting the reaction product “D” with a fifth agent to form a Ziegler-Natta catalyst, wherein the fifth agent includes an organoaluminum compound.
摘要:
This disclosure relates to a ligand compound, a catalyst system for olefin oligomerization, and a method for olefin oligomerization using the same. The catalyst system for olefin oligomerization according to the present invention has excellent catalytic activity, and yet, exhibits high selectivity to 1-hexene or 1-octene, thus enabling more efficient preparation of alpha-olefin.
