    54) METHOD OF OBTAINING CHLORIDE ALYUGH
    one
    The invention relates to methods for producing aluminum chloride that is widely used for the electrolytic production of aluminum, as well as in organic synthesis as a catalyst for Fritdel Crafts reactions.
    A known method for producing aluminum chloride by chlorinating apium-containing raw materials in the presence of a gaseous or solid reducing unit in a fluidized bed furnace.
    There is also known a method for producing aluminum chloride by chlorinating an aluminum-containing raw material in a melt of aluminum chlorides and whole metals in the presence of a solid reducing agent. T The disadvantage of this method is the low utilization of chlorine (-v. 50%)
    The aim of the invention is to increase the use of chlorine.
    This goal is achieved by the described method of producing chlorine aluminum, which implies that aluminum-containing raw materials are chlorinated in a melt of aluminum and alkali metal chlorides in the presence of solid. dog reductant, and the concentration of
    The concentration of aluminum chloride in the melt is maintained equal to 30-80 wt.%.
    A distinctive feature of the present invention is that the concentration of aluminum chloride in the melt is maintained at 30-80% by weight.
    This difference makes it possible to achieve 100% chlorine use.
    When the concentration of aluminum chloride in the melt is less than 30 wt.%, The degree of use of chlorine is significantly reduced, so with a 1% content of AyCl2 in the melt, only 3% of the introduced chlorine is converted to aluminum chloride.
    Example. The composition for chlorination containing by weight approximately 50% sodium chloride, 25% lithium chloride, 25% aluminum chloride is heated in the bath to a temperature of approximately using resistance heaters. Coal and alumina, crushed to sizes of 325 (according to Taylor), are added to the composition indicated, on a calculus basis. 0.007 kg of coal and 0.027 kg of alumina per 0.45 kg of the composition in the bath. After that, chlorine is passed to the bottom of the bath at a rate of approximately 0.31 F / h (0.14 kg / h) and
    coal and alumina are added in amounts of approximately 0.02.63 f / h (0.012 kg / h) and 0.149 f / h (ri 0.07 kg / h), respectively, in order to maintain an excess of these substances in relation to chlorine . The bath is filled with Raschig rings to allow for uniform distribution of chlorine.
    The concentration of aluminum chloride in the melt reaches approximately 42% of the composition in the bath. Then the aluminum chloride is evaporated from the bath and its waste stream is generated by the method of selective separation. In conclusion, the purified aluminum chloride vapors are regenerated by condensation, the chlorine chloride aluminum chloride is 99.9%.
    Example2. Compounds are prepared for chlorination by mixing approximately 169 pounds (kg) of sodium chloride and 395 pounds (vl79 kg of aluminum chloride, melting the mixture and heating it to a temperature of approximately 825 seconds. An excess of approximately 0.135 kg of coal and 0.135 kg of alumina per 0.45 kg melt in a bath. Chlorine gas is then passed at a rate of approximately 245.1 f / h (kg / h) and coal is added in an amount of approximately 90.8 f / h (9.4 k-g / h) and alumina in an amount of 116 , 3 f / h (50 kg / h),
    Aluminum chloride is regenerated at a rate of approximately 304.1 f / h (kg / h) and the mixture of sodium chloride and aluminum is recycled to the chlorination bath at a rate of approximately 805.3 f / h (kg / h).
    The chlorination bath is a container with a diameter of approximately 18 inches (v457 mm) and a height of approximately -58 inches (mm).
    The rotation speed of the stirrer is 300 rpm.
    The size of the alumina particles 100 according to Taylor.
    Chlorine aluminum chloride yield
    is 99%.
