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) existed in an 3 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 Fe3+ into Fe2+. The reaction between Fe2+ and bipy generated a Fe (bipyridine)2+ complex compound, which prevented Al (i-Bu)3 from reducing Fe2+ to a lower valence (Fe+, Fe0). The excessive Al (i-Bu)3 was dissociated into ion pairs and formed a double layer, which stabilized the nano-sized particles.
