FIELD: fluidization at heterogeneous process of production of organochlorsilanes by interaction of contact mass consisting of finely dispersed silicon and copper-based catalysts with gaseous chlorine alkyl. SUBSTANCE: reactor has housing, tubular heat exchanger, contact mass loading and unloading units, units for supply and discharge of gaseous component and finished product; gas distributor is made in form of tubular spiral with holes for escape of gaseous component at 60 to 90 deg. relative to surface of reactor bottom; spiral is rigidly secured on cross-piece provided with central ring-shaped opening; cross-piece is mounted in lower portion of reactor and is secured in its housing; spiral is equidistant relative to surface of reactor bottom. EFFECT: increased productivity of reactor. 5 dwg
