Abstract

Organochlorosilanes are produced by reacting, in a fluidized bed reactor, a chloromethane-containing reactant gas with a particulate contact mass containing silicon and a catalyst, wherein the organochlorosilanes have the general formula (CH3)nHSiCl4-n-m where n=1 to 3 and m=0 or 1, wherein the process is characterized by three dimensions indices K1-K3, which are respectively associated with the reactor, the contact mass, and the reaction conditions, and which are maintained within specified bounds.
