Ethylene Tri- and Tetramerization with Borate Cocatalysts: Effects on Activity, Selectivity, and Catalyst Degradation Pathways
摘要:
Chromium-based ethylene tri- and tetramerization catalysts have been evaluated with a combination of trialkylaluminium and borate cocatalyst activation. A remarkable effect on activity and selectivity has been observed and studied, and a cocatalyst-induced degradation pathway has been identified.

producing 1-hexene and 1-octene is by oligomerization of ethylene, which yields a wide spectrum of linear alpha-olefins (LAOs). While there exists several processes for producing 1-hexene via ethylene trimerization, a similar route for the selective production of 1-octene has so far been elusive. We now, for the first time, report an unprecedented ethylene tetramerization reaction that produces 1-octene
