Interaction between the Components of FeCl3-Al(i‐Bu)3-bipyridine Catalyst

The interactions between the components of FeCl3-Al (i-Bu)3-bipyridine -catalyst were studied by the electric conductivity of these components in a hydrogenated gasoline medium at 25℃. It was found that Al (i-Bu)3 existed in an associated state and was then dissociated into ion pairs. The reaction between FeCl3 and Al (i-Bu)3 is the chief reaction in the formation of nano-sized particles. Simultaneously, Al(i-Bu)3 reduced Fe^3+ into Fe^2+. The reaction between Fe^2+ and bipy generated a Fe (bipyridine)^2+ complex compound, which prevented Al(i-Bu)3 from reducing Fe^2+ to a lower valence(FC^+, Fe^0). The excessive Al (i-Bu)3 was dissociated into ion pairs and formed a double layer, which stabilized the nanosized particles.
