    专利说明:

    The invention relates to methods for producing a silicon reaction mass used in the manufacture of methyl chlorosilanes.
    . The aim of the invention is to increase the efficiency of the reaction mass in the process of producing methylchlorosilane by providing it with a copper content of 1.56 wt%.
    Example. 97.06 mash of silicon particles (65x150 mesh), 2, 7 mash of cement type copper (uniformly oxidized, containing 10.9% metallic copper, 43.9% CuijO, 43.9CuO) are mixed in a double shell mixer. and 84.9% of total copper) with a size of 2-5 microns and 0.24 wt.h. zinc dust.
    Mixed powders are treated in a Ni-Cr rotary kiln with a diameter of 6-1 / 2 inches (15.24-1.27 cm)
    with flue gases under the following conditions: temperature 1000 ° C, mass loading 1200 g / h; unloading mass of 1030 g / h; furnace load 5.3 vol.%; residence time 61 minutes; flow Hj, 4800 cm / min; a gas velocity of 0.06 ft / s (0.018 m / s, H2: CuO 30: 1.
    The resulting reaction mass is unloaded from the furnace and analyzed.
    I
    The mass obtained as a free flowing powder contains 1.56% by weight of copper, of which 90% is in the form of an alloy. The resulting mass is subjected to interaction with methyl chloride to obtain methyl chloroilanes in a fluidized bed reactor of carbon steel with a diameter of 1 inch (2.54 cm) at 320 ° C.

    Wila 31.1 g / h, and the coefficient of selectivity is 14,
    In accordance with the prototype, equivalent re- sults could be achieved only if the reaction mass contained 7% copper.
    The feasibility of the method lies in the fact that, unlike the prototype, where the mass is formed in the form of porous sintered granules, this method produces a free-flowing powder with a 3.5 times lower copper content. Copper-catalyzed silicon mass, obtained by the proposed method, also has the following advantages: essentially, there is no induction period in the process of producing methylchlorosilane monomers; less copper catalyst required; it is possible to achieve a higher reaction rate and higher selectivity; into wholesome foods
    translates more flint. In addition, the reaction to produce methyl chlorosilanes is more stable and less sensitive to the source of the copper catalyst.
