【Abstract】 Montmorillonite-iron(Ⅲ)catalyst is prepared.By means of X ray powder diffraction and electron microscope the structural properties of the catalyst are studied.Fe(Ⅲ) exists in the lager of montmorillonite-iron catalyst.The structure of montmorillonite has no change.The quartz composition in the catalyst is about 22%～24%.The structural defecd of montmorillonite in EC 1 and EC 2 is less than that of EC 4,EC 5 and EC 6.The rate of transformation is high and the velocity is rapid when EC 4,EC 5 and EC 6 are used as catalysts,at the same time the separation is simple and can be used repeatedly更多还原
