    Abstract: A method for the recovery of anhydrous aluminium chloride from a mixture of the aluminium chloride with ferrous chloride or ferric chloride, or both, which comprises subjecting the liquid mixture to a reduction in pressure, the conditions being such as to bring about dissociation of compounds of aluminium chloride and ferrous chloride present in the mixture, thereby to form an aluminium chloride-rich vapour and an iron chloride-rich solid and then separately collecting of the iron-and aluminium-rich components under conditions which give the minimum opportunity for recombination.

    Abstract: An improved process for the production of aluminum chloride from coked alumina and chlorine comprises providing a bed of coked alumina in a reaction vessel and introducing gaseous chlorine thereto in an amount sufficient to fluidize the bed, at least a portion of the vessel having a nitride-based refractory lining especially adjacent and bounding the lower part of the fluidized bed. Aluminum chloride formed is recovered as a gaseous effluent emmanating from the bed.

    Abstract: A process of carbo-chlorination of AlPO.sub.4 wherein AlPO.sub.4 or AlPO.sub.4 -containing material is introduced into a reactor along with chlorinating agents and a source of carbon. The reactor is heated to approximately 600.degree. to 1200.degree.C and forms aluminum chlorides, phosphorous oxides, phosphorous chlorides, phosphorous oxychlorides and carbon oxides. These reaction products are then separated into three fractions by condensation, the first fraction being P.sub.2 O.sub.5, the second fraction being AlCl.sub.3 and AlCl.sub.3 .POCl.sub.3 and the third fraction being remaining gasses, namely PCl.sub.3, PCl.sub.5, P.sub.2 O.sub.3, CO and CO.sub.2. The second fraction is reacted in a further reactor to give AlCl.sub.3 and P.sub.2 O.sub.3 which are separated by distillation. The phosphorous chlorides from the third fraction are oxidized, along with the P.sub.2 O.sub.3 of the second fraction, to form P.sub.2 O.sub.5.

    Abstract: A continuous process for producing aluminum trichloride by reacting in a fluid-bed reactor, at 310*-580*C, a chlorinecontaining gas with a fluidised bed of aluminum particles, which comprises feeding the chlorine-containing gas at the bottom of the fluidised bed of aluminum particles, through a gas distributor whose upper surface is inclined with respect to the vertical and discharging continuously said fluidised bed of aluminum particles through an outlet means which is located at the lowermost part of said inclined upper surface. The dischared particles are then cooled and recycled to the top end of the fluidised bed with fresh aluminum particles. At the top of the fluid-bed reactor, an aluminum trichloride containing gaseous stream is discharged and aluminum trichloride is separated therefrom.
