CPC C07F 7/16 (2013.01) [B01J 23/72 (2013.01)] | 13 Claims |
1. A process for producing methylchlorosilanes of general formula 1
(CH3)nHmSiCl4-n-m (1),
in which
n represents values from 1 to 3 and
m represents values of 0 or 1
in a fluidized bed reactor, wherein a chloromethane-containing reaction gas is reacted with a particulate contact mass containing silicon in the presence of copper catalyst,
wherein an operating granulation, i.e. the granulation or granulation mixture introduced into the fluidized bed reactor, contains at least 1% by mass of silicon-containing particles S described by a structural parameter S, wherein S has a value of greater than 0 and is calculated as follows:
wherein
φS is symmetry-weighted sphericity factor
ρSD is poured density [g/cm3]
ρF is average particle solids density [g/cm3].
