Title:
リガンド、それを含むオリゴマー化触媒、およびそれを用いたエチレンオリゴマーの製造方法
Document Type and Number:
Japanese Patent JP7210552
Kind Code:
B2
Abstract:
The present invention relates to a ligand, an ethylene oligomerization catalyst comprising same, and a method for selectively producing 1-hexene or 1-octene from ethylene by using the catalyst. The ligand according to the present invention is a bis(diphenylphosphino)ethene with a phosphorus atom substituted with a fluoro-substituted phenyl, and when the ligand is used for ethylene oligomerization, the high temperature activity of the catalyst can be increased.
