HALOGEN-CONTAINING COMPOUND AND USE THEREOF, CATALYST COMPOSITION, AND ETHYLENE OLIGOMERIZATION, TRIMERIZATION AND TETRAMERIZATION METHODS

WIPO Patent Application WO/2020/147373

A1

Disclosed are a halogen-containing compound as shown in formula I and the use thereof as a ligand for an ethylene oligomerization catalyst composition; and further disclosed are an ethylene oligomerization catalyst composition containing the halogen-containing compound, and ethylene oligomerization, trimerization and tetramerization methods using the catalyst composition. As a ligand of a catalyst for ethylene oligomerization, a fluoropolymer can effectively improve the catalytic performance of a catalyst system, and particularly exhibits significantly improved activity and selectivity in an ethylene oligomerization reaction. The catalyst composition has better industrial application prospects and economic value.
