摘要: Abstract A diphosphinoamine ligands has been synthesized. In combination with Cr(III), methylalumoxane (MAO) and tetrachloroethane (TCE), they generate active catalytic systems for ethylene tetramerization toward 1-octene. The effects of reaction temperature, pressure, molar ratio Al/Cr, TCE/Cr, ligand/Cr, time sorts cocatalyst on activity selectivity to 1-octene were studied. results show that the diphosphinoamine/Cr(III)/TCE/MAO four-membered have improved 1-octene, but is lower than three component system. MAO requisite in forming species TCE shows significant promotion effect assist chromium center improving
