    Abstract: Basic aluminium chlorides of the formula Al2OHnCl6-n (where n is a number between 4 and 5) are prepd. by treating aq. solns. contg. Aluminium chloride with solns. of amines (in effect a liquid ion-exchanger, having advantages of insensitivity to impurities and ease of regeneration of molecular weight 250-500 (pref. primary, secondary or tertiary monoamines) in a water-immiscible organic solvent (pref. petroleum, kerosene or xylene), separating the aq. phase and recovering the basic aluminium chloride. The aq. phase must not contain >25 g Al per litre, and the organic phase must not contain > 0.35 mol amine per litre. Basic aluminium chlorides are used in the cosmetic and pharmaceutical sectors as components of antiperspirants and haemostatic agents. They are also used for hydrophobizing textiles, as tanning agents, as flocculating and phosphate-precipitating agents, and in the production of fire resistant materials.

    Abstract: Production of Si-containing Fe powder comprises thermally decomposing a gas mixture containing Fe-pentacarbonyl and a volatile Si-compound. The volatile Si-compound is a silane or organosilane, except triethylsilane and tetraethoxysilane. Also claimed is an apparatus for carrying out the process comprising: (a) a heated decomposition pipe; (b) a device for adjusting two different temperature zones; (c) a device for vaporising liquid Fe-pentacarbonyl; (d) a device for dosing and mixing gases; and (e) a separator for Si-containing Fe powder.

    Abstract: A process for producing finely divided phosphorus-containing iron involves gaseous phase reaction of iron pentacarbonyl with a phosphorus compound, preferably phosphine. Preferably, the reaction is carried out in the presence of ammonia at above 200 degrees C. Also claimed is a finely divided phosphorus-containing iron which consists of spherical particles with 1-10 mu mean particle diameter or of filament aggregates of spheres with 0.2-3 mu diameter. Preferably, the iron contains 0.1-50 wt.% P, less than 1 wt.% C, less than 1 wt.% N, less than 0.5 wt.% H and less than 0.1 wt.% total of other impurity elements and is produced by the above process. Further claimed is apparatus for carrying out the above process, including a heated decomposition tube, devices for producing two different temperature zones, for evaporating liquid iron pentacarbonyl and for gas dosing and mixing, and a separator for finely divided phosphorus-containing iron.
