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.degree. to 700.degree. C. The .gamma.-alumina used gives, with CuK.sub..alpha. radiation, an X-ray diffraction pattern whose intensity at the diffraction angle 2.sup..crclbar. =42.8.degree..+-.0.4.degree. divided by the intensity at the diffraction angle 2.sup..crclbar. =45.7.degree..+-.0.2.degree. is .ltoreq.0.38.
