A process for the tetramerisation of ethylene under solution phase conditions is carried out in the presence of an activated catalyst at a temperature above 80°C and up to a temperature of about 130°C. The activated catalyst is provided by combining a source of chromium, a ligating compound, which ligating compound includes at least one fluorine substituted hydrocarbyl group, organoheteryl group, or heterohydrocarbyl group, and optionally a catalyst activator or combination of catalyst activators.
在溶液相条件下,通过在80°C以上且高达约130°C的温度下,在活化催化剂存在下进行
乙烯四聚化的过程。所述活化催化剂通过结合一种
铬源、一种配位化合物(该配位化合物包括至少一个
氟代烃基、有机杂原子基团或杂原子有机基团),以及可选的催化剂活化剂或催化剂活化剂组合提供。
