Cryosynthesis of catalysts for propylene oligomerization based on titanium tetrachloride and magnesium

Article abstract of DOI:10.1007/BF02494632

A highly dispersed catalyst for oligo- and polymerization of propylene was synthesized by the interaction of TiCl₄ with magnesium in the cocondensates of their vapor with benzene and pentane. The catalyst contains MgCl₂ and organotitanium and organomagnesium cluster derivatives. The transformations of propylene and hex-1-ene over the catalysts were studied. The direction of catalytic reactions and activity of the catalyst depend on the TiCl₄ : Mg molar ratio and the hydrocarbon used. Systems with an equimolar ratio of the reactants obtained in a benzene matrix exhibit the highest activity. Propylene oligomers containing a considerable fraction of unsaturated bonds are formed in the presence of the catalysts at room temperature and a pressure of 300 Torr.
