摘要：

研究了异辛酸铬[Cr（Ⅲ）2-EH]/2,5-二甲基吡咯（DMP）/双膦胺型配体（PNP）/三乙基铝（TEA）/1,1,2,2-四氯乙烷（Cl₂CHCHCl₂）催化体系对乙烯三聚反应催化剂的活性和1-己烯的选择性的影响。结果表明，复配体系能同时获得高活性和对1-己烯的高选择性。在反应温度120 ℃、压力5.0 MPa下，催化活性达到270 kg/(gCr·h)以上，1-己烯选择性超过95%，与单一配体DMP和PNP的催化性能相比较，综合了两者的优势。

Abstract:

The catalytic activity of the catalyst system composed of Cr（Ⅲ）2-ethylhexanoate [Cr（Ⅲ）2-EH]，2,5-dimethylpyrrole（DMP），diphenylphosphinoamine（PNP），triethylaluminium（TEA）and 1,1,2,2-tetrachloethxane in ethylene trimerization and the selectivity for 1-hexene were studied. The results showed that the catalyst system improved the activity and selectivity simultaneously. A catalyst activity exceeding 270 kg/gCr per hour was achieved at 120 ℃ and 5.0 MPa，and the selectivity for 1-hexene was more than 95%. Compared with the single ligand DMP or PNP，the catalyst system with composite ligands combined their respective advantages.
