    An improved method is disclosed for producing aluminum chloride by contacting chlorine with aluminum oxide and a reducing agent, each of which is present in an amount in excess of the stoichiometric amount of the chlorine in a molten bath of aluminum chloride and metal halide to form aluminum chloride which is recovered from the bath by sublimation. The improvement comprises increasing the rate of formation of aluminum chloride by adding a source of metal selected from the group consisting of iron, chromium, copper, europium and cerium to the molten bath.

    The invention relates to methods for producing aluminum chloride, which can be used as a catalyst in the cracking of petroleum products, as well as a number of organic syntheses.
    A known method of producing aluminum chloride by chlorination in a fluidized bed of aluminum-containing raw materials in the presence of a gaseous booster and melted particles of sodium aluminum chloride [1].
    There is also a method of producing aluminum chloride by chlorination of aluminum-containing raw materials in the presence of a reducing agent in a melt of aluminum and sodium chlorides [2].
    The disadvantage of this method is not sufficiently high speed Xia chloride (rirovaniya (at a flow rate 'chlorine Umino 300 cm) completeness of its conversion is 41-52%.
    The purpose of this invention is to increase the rate of chlorination. .
    The goal is achieved by the described method for producing aluminum chloride by chlorinating an aluminum-containing raw material in the presence of a reducing agent in a melt of aluminum and sodium chlorides or iron chloride, or monovalent copper chloride, or divalent copper chloride, or chromium chloride, which take, respectively, the weight. %: 0.05-10; 0.05—5; 0.07 7-1.
    A significant difference of the invention is that the process is conducted in the presence of either iron chloride, or monovalent copper chloride, or divalent copper chloride, or chromium chloride.
    It is preferable to take them in an amount, respectively, wt.%: 0.05-10; 0.05-5; 0.077-1.
    These differences can significantly increase the rate of chlorination (at a rate of transmission of chlorine of 300 cm e / min> the completeness of its conversion is 84%.
    Example 1. In a salt melt containing 390 g of NaCC, 920 g of AECE ^, at a temperature of 788 ^ 0, 325 g of coke, crushed to 100 mesh, and 50 g of A6 2 Oj, also crushed to 100 mesh, are introduced. Chlorine gas is passed through the melt, which enters the lower part of the melt bath at a speed of 300 cm ^ / min. The completeness of the conversion of chlorine to aluminum chloride · ν 4 1%. In the next experiment, the melt is introduced Ciss 2, in an amount of 1.0 g per 100 g NaCE-Al'CC ,.
    while the completeness of the conversion of chlorine to A8. SC for the same time as in the first case, increased to 84%.
    Example 2. The process is carried out in the same way as in example 1, but subsequently CuBR is introduced into the melt in the amount of 0.077 g per 100 g of NaCe-Atce 3 , while the completeness of chlorine conversion in the forest, at the same time, increased to 73%.
    Example 3. The process is carried out as in example 1, but subsequently 1.0 g of FeCC ^ per 100 g of NaCe-A £ Ce d is introduced into the melt.
    The completeness of the conversion of chlorine 69%.
    Example 4. The process is carried out as in example 1, but 1.0 g of chromium chloride is introduced into the melt.
    The completeness of the conversion of chlorine is 53%.

    The invention relates to methods for producing aluminum chloride, which can be used as a catalyst in the cracking of petroleum products, as well as a number of organic syntheses. A method of producing aluminum chloride by chlorinating aluminum-containing gas in the fluidized bed in the presence of a gaseous reducing agent and molten sodium aluminum chloride particles 1 is known. A method of producing aluminum chloride by chlorinating aluminum-containing raw material in the presence of molten aluminum chloride in a molten aluminum chloride by means of chlorinating aluminum-containing raw materials in the presence of aluminium chloride 1 is also known. The chlorination rate is not high enough (at a chlorine transmission rate of 300 cm of umin), the completeness of its conversion is. The purpose of this invention is to increase the rate of chlorination. This goal is achieved by the described method of producing aluminum chloride by chlorinating aluminum containing raw materials in the presence of a reducing agent in a melt of aluminum and sodium chlorides or iron chloride. or monovalent copper chloride, or divalent copper chloride, or chromium chloride, which is taken in an amount of, respectively, wt.%: O., 05-10; 0.05-5; 0.077-1. The essential difference of the invention is that the process is carried out in the presence of either ferric chloride, or monovalent copper chloride, or divalent copper chloride, or chromium chloride. It is preferable to take them in quantity, respectively, wt.%: 0.05-10; 0.05-5; 0.077-1. These differences make it possible to significantly increase the rate of chlorination (at a rate of 300 cm / min. Chlorine, the conversion is 84% complete. Example 1. In a salt melt containing 390 g of NaC, 920 g AECE, 325 g coke crushed to 100 mesh, and 50 g ABjO.j, also crushed to 100 mesh. Chlorine gas is passed through the melt, which enters the bottom of the molten bath at a rate of 300. Conversion of chlorine to aluminum chloride 4 1%. following experiment, CuCCj i is introduced into the melt in the amount of 1, 0 g per 100 g of NaCE-AlCC ,, J ... 73 with This completes the conversion of chlorine to ASC for the same time as in the first case, increased to 84%. Example 2. The process is carried out as in Example 1, but later CWS is added to the melt in a quantity of 0.077 g per 100 g NaCe-Aece t in this case, the completeness of chlorine conversion in the forest increased to 73% over the same time. Example 3. The process is carried out as in Example 1, but 1.0 g of FeCg-j is introduced into the melt per 100 g of Nace-Aece,). Completeness of chlorine conversion 69%. Example 4. The process is carried out as in Example 1, but 1.0 g of chromium chloride is introduced into the melt. The chlorine conversion is 53%. Claim 1.
