Abstract (en)
[origin: WO2016091551A1] The invention relates to a method for the production of methyl chlorosilanes by reaction of chloromethane with a contact mass, in which a mixture containing silicon, copper catalyst and promoter (contact mass 1) is fed into a first fluidized-bed reactor (fluidized-bed reactor 1), active contact mass (contact mass 2) is formed in the presence of chloromethane at 200 to 450 °C, a part of the contact mass (2) is removed from the fluidized-bed reactor (1) and fed into a second fluidized-bed reactor (fluidized-bed reactor 2) and reacted at 200 to 450°C with chloromethane, wherein, per time unit in fluidized-bed reactor (1), at least 20 parts by weight of contact mass 2 per 100 parts by weight of contact mass (1) are recycled, and wherein contact mass (2) fed into fluidized-bed reactor (2) and recycled in fluidized-bed reactor (1), is not cooled to a temperature below 150 °C after removal from the fluidized-bed reactor (1).
