Abstract: Anhydrous aluminum chloride is prepared by reacting gamma -alumina with carbon monoxide and chlorine and/or phosgene in a fluidized bed at from 400 DEG to 700 DEG C. The gamma -alumina used gives, with CuK alpha radiation, an X-ray diffraction pattern whose intensity at the diffraction angle 2(-)=42.8 DEG +/-0.4 DEG divided by the intensity at the diffraction angle 2(-)=45.7 DEG +/-0.2 DEG is
