摘要:
从乙烯选择性四聚催化体系铬配合物的配体结构(双膦胺型配体、乙基桥连双膦型配体、碳-氮桥连磷胺型配体)、助催化剂和反应机理等方面,综述了近年来乙烯选择性四聚领域内的研究进展,指出过渡金属铬配合物在乙烯选择性齐聚中具有高催化活性、产物高选择性的特点,是制备1-己烯、1-辛烯等线性α-烯烃的主要催化剂,配体结构是影响铬配合物结构和催化活性中心性能的关键因素。
Abstract:
Ligand structure, which include biphosphine amine , ethyl bridged biphosphine and carbon-nitrogen bridged phosphine amineligands, together with co-catalyst and reaction mechanism of chromium complexes had been used to analyze recent research progress in the field of selective tetramerization of ethylene with 22 references. The transition metal chromium complex had been found excellent catalytic activity and product specificity in selective oligomerization of ethylene, and was studied as the principal catalyst for the synthesis of linear-olefins such as 1-hexene and 1-octene, according to reports. The ligand structure was found to be a key factor that affecting the structure of the chromium complexes and the performance of the catalytical active center.
