Ethylene Oligomerization Catalyzed by Organosilane-Modified Solid Catalysts

Abstract

The oligomerization of ethylene was carried out on PhSiH₃-modified ZrO₂ and TiO₂. Upon silylation with PhSiH₃, the activity in the activity oligomerization of ethylene were newly generated on ZrO₂ and TiO₂. The oligomers consisted of 1-hexene(66%) on ZrO₂ at PhSiH₃ coverage of 0.1 and the oligomers consisted of 1-butene(80%) on TiO₂ at PhSiH₃ coverage of 0.45. We examine the effect of PhSiH₃ coverage and adsorption pressure on the selectivite formation of 1-butene or 1-hexene on PhSiH₃-modified oxides.
