Ethylene Trimerisation based on Chromium Catalyst with Pyrrolil Ligands

In homogeneous chromium-based catalyst system [Cr(III) tris(2-ethylhexanoate)/ pyrrole/AlEt3/hexachloroethane (HCE) ], the effect of Al/Cr molar ratio compound to 1-hexene formation selectivity and catalytic activity was investigated. The results showed that triethylaluminum (TEA), was effective cocatalyst for ethylene trimerization toward 1-hexene. With the increasing of Al/Cr molar ratio, the selectivity to 1-hexene was decreased and the catalytic activity obvious decreased
