Abstract
Provided is a plant for the continuous production of monosilane and tetrachlorosilane by catalytic dismutation of trichlorosilane, wherein the plant contains: a countercurrent reactor having a double wall, a catalyst bed containing a catalyst which is located in the countercurrent reactor, a condenser at the top of the countercurrent reactor, a vaporizer unit at the bottom of the countercurrent reactor, a trichlorosilane feed line for the introduction of trichlorosilane into the countercurrent reactor, a heat exchanger, with the trichlorosilane conveyed by line via the heat exchanger and preheated there by a bottom product from the vaporizer unit and, for this purpose, the bottom product is fed by line via the heat exchanger into the double wall at a level in the lower part of the countercurrent reactor and discharged from the double wall at a level in the upper part of the countercurrent reactor, a condensation unit downstream of the condenser, and a distillation column having an outlet for monosilane.
