有机铝催化剂中吸电子取代基对丙烯齐聚催化性能的影响

THE EFFECT OF ELECTRON WITHDRAWING GROUPS IN ORGANO-ALUMINIUM CATALYSTS ON CATALYTIC PERFORMANCE FOR PROPYLENE OLIGOMERIZATION

在以甲苯为溶剂,乙酰丙酮镍和取代的烷基铝作催化剂的均相体系中,研究了氯原子和硝基取代基对催化剂性能的影响,并结合反应机理对其原因进了探讨。

The effects of chlorine atom and nitro-substituting group on the performance of catalyst in homogeneous system, with the toluene as solvent and the nickel acetylacetonate and substituted alkyl aluminium as catalysts,were studied,and the causes were discussed with the reaction mechanism.
