摘要: Abstract Ethylene tetramerization with PNP/Cr(III)/aluminoxanes was investigated. By comparing catalytic activity, selectivity to 1-octene and methylenecyclopentane in ethylene tetramers, the effects of various aluminoxanes on were discussed. The results showed that MMAO(TMA-depleted), MAO EAO all effective cocatalyst for toward 1-octene. PNP/Cr(III)/MMAO systems afford highest activity selectivities decreased by using i-BAO as cocatalyst, which indicated different mechanism has been occurred such cases.
