Selective Synthesis of Butene-1 Through Double-bond Migration of Butene-2 over η-Alumina Catalysts

摘要

Double bond migration of butene-2 to butene-1 over η-alumina was investigated. The effects of calcination temperature on catalytic properties were analyzed by applying BET surface area, XRD, NH3-TPD, and FT-IR of adsorbed pyridine techniques. The highest activity of the η-alumina catalyst calcined at 600 oC could be attributed not only to the highest amount of weak and medium strength acid sites, but also to the highest ratio of medium to weak strength Lewis acid sites.
