Description
Summary:[Display omitted] ► NaNp/CpTiCl3/Al2O3SiO3 olefin isomerization catalysts. ► Hexene-1/Ti=100:1; 60°C; 2h. ► Hexene-1 conv.=83% (100% Al2O3); 72% (60% Al2O3); 6% (30% Al2O3); 28% (100% SiO2). NaNp/CpTiCl3/Al2O3SiO2 (Cp=cyclopentadienyl; Np=napthenide anion) systems are new catalysts active in the CC hexene-1 bond isomerization reaction. Their activity depends on amount of titanium[III] hydride surface complexes and the support Lewis acidity. As results showed, all these properties are a function of the Al2O3SiO2 gels composition. The highest yields were obtained for the 90 and 100wt.% Al2O3 catalysts (Lewis acidity) and for the 10 and 60wt.% Al2O3 catalysts (amount of Ti[III]+Lewis acidity).
