摘要： Disclosed are a halogen-containing compound as shown in a formula I and 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.

摘要： A halogen-containing compound represented by a formula I and a use thereof as a ligand of an ethylene oligomerization catalyst composition, an ethylene oligomerization catalyst composition comprising the halogen-containing compound, and an ethylene oligomerization method, ethylene trimerization method and ethylene tetramerization method using the catalyst composition. Serving as the ligand of the ethylene oligomerization catalyst, the halogen-containing polymer may effectively improve the catalytic performance of a catalyst system, especially by displaying a significantly improved catalytic performance in an ethylene oligomerization reaction. The maximum catalyst activity may exceed 4 × 10 8 g•mol(Cr) -1 •h -1 , and the total selectivity of 1-hexene and 1-octene exceeds 92 wt%. In a C6 product, the content of 1-hexene may reach about 97%, and in a C8 product, the content of 1-octene may reach more than 98%. The present catalyst composition has good industrial application prospects and economic value.
