A description is given of a process for the oligomerization of α-olefins having at least 3 carbon atoms, in which the olefin is brought into contact with a catalyst system obtainable from a chromium source, a 1,3,5-trialkyl-1,3,5-triazacyclohexane, where the alkyl radical has no α, β or γ branching, and at least one activator comprising a boron compound, with the molar ratio B:Cr being at least 5. The process allows the preparation of trimers of the α-olefin in high yield and with high selectivity.
本发明描述了一种至少具有 3 个碳原子的 α 烯烃的低聚工艺,在该工艺中,烯烃与可从
铬源获得的催化剂体系、1,3,5-三烷基-1,3,5-三氮杂
环己烷(其中烷基没有 α、β 或 γ 支化)以及至少一种由
硼化合物组成的活化剂接触,B:Cr 的摩尔比至少为 5。该工艺可以高产率、高选择性地制备 α 烯烃的三聚体。
