The reaction kinetics of the isomerization 3,4-dichlorobutene-1 to 1,4-dichlorobutene-2 was investigated by using gas-liquid chromatography method in the presence of Fe2O3/MgO as solid catalyst in the temperature range 25-55°C. Fe2O3/MgO has been prepared by the support saturation method, tested in the isomerization of 3, 4-dichlorobutene-1 into 1, 4-dichlorobutene-2. This catalyst shows a high activity opposite to pure MgO in this reaction. The present investigation focuses on the reactivity of Fe2O3/MgO with the 5 wt % Fe2O3 on the surface of MgO. At the optimizing conditions, the activation parameters have been evaluated using the Arrhenius and Eyring plots. The structure of catalyst was investigated by using Mossbauer spectroscopy.
