摘要
采用FTIR方法研究乙烯三聚制备 1 己烯催化剂的配位方式。结果表明 ,在该催化剂体系 (异辛酸铬 /三乙基铝 /烷基吡咯 /四氯乙烷 )中存在几种不同结构的配位化合物 。
In this paper the coordinate mode of the catalyst system for the selective trimerization of ethylene to 1-hexene was investigated by Fourier transform infrared spectroscopy (FTIR). The results indicate that several coordinate chemical compounds exist in this catalyst system Cr(2-ethylhecanoate)_3/triethylaluminum/dimethylpyrrole/tetrachloroethane, which play different roles in the process of the selective trimerization of ethylene to 1-hexene.
