Embodiment 1
[0028] 1. Catalyst synthesis of chlorinated 2,6-bis(2-benzimidazolyl)pyridine chromium(III) complexes
[0029] According to the preparation method reported in the literature (Organometallics.2006,25,1961-1969), 2,6-bis(2-benzimidazolyl)pyridine chromium(III) chloride was prepared, R 1 -R 5 Both are hydrogen.
[0030] 2. Ethylene oligomerization reaction, which specifically includes the following steps: (1) replace the reaction system by high temperature drying, vacuum replacement and other operations to ensure that there is no water and oxygen in the reaction system; (2) use ethylene to replace the reaction system, Make the reaction system in an ethylene environment; (3) add tert-butyl hydroperoxide and toluene solvent in the reaction kettle, add 1.37ml triethylaluminum toluene solution (concentration is 715μmol / ml), add 2ml 2,6-chloride After the toluene solution (concentration is 2.5 μ mol / ml) of two (2-benzimidazolyl) pyridine chromium (III) complexes, the total amount of...
