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.
在溶液相条件下进行
乙烯四聚化的过程,需要在80°C以上的温度下,并且最高温度可达130°C。该过程需要使用激活催化剂,该激活催化剂由
铬源、配位化合物和至少含有一个
氟代烃基、有机杂环基或杂
环烃基的配位化合物组成,并且可选地加入催化剂活化剂或催化剂活化剂组合。
