The catalytic properties of a series of cobalt complexes containing monodentate phosphorus, bidentate phosphorus, bidentate
nitrogen ligand for displacement reaction of trialkylaluminum with ethylene is reported. Effect of reaction time, temperature
and different ligands on catalyst performance has been investigated. The kinetics of the reaction of tri-isobutylaluminum
with ethylene catalyzed by zerovalent cobalt complex has been studied. The displacement reaction rate shows first-order
dependence with respect to trialkylaluminum concentration, cobalt complex concentration and ethylene pressure, respectively.
The kinetics equation of displacement reaction rate is r = 1.4×106 [R3Al][Cat][PC2H4 ]. The activation energy for this reaction
is Ea = 71.9 kJ/mol. 便携式车载气相色谱仪
