The invention relates to a method for producing organochloriosilanes in a fluid bed reaction by reacting reaction gas containing an organic compound, with chlorine bound to carbon, with silicon containing contact mass, copper catalysts and promoters, in which the fluid bed reaction is carried out in a fluid bed reactor, wherein the hydraulic diameter of the fluid bed reactor dhyd, the empty tube gas velocity in the fluid bed reactor UL and the particle Sauter diameter of the contact mass d32 are chosen in such a way that, in a Cartesian coordinate system in which Ar is plotted against Re, points are formed on the area, wherein the area is delimited by equations 1 and 2. Equation 1 : Ar = 2.10-5 Re2 + 0.08 * Re - 120. Equation 2 : Ar = 2.10-5 Re2 -1.07 * Re + 14100 wherein the lower limit is Ar = 0.5 and the upper limit is Ar = 3000, wherein Ar and Re are determined as described in claim 1. The invention further relates to a method for selecting reaction parameters for the production of organochlorosilanes.
