Abstract

Silane is produced in a continuous process by disproportionating trichlorsilane in at least 2 recreation areas for reaction/distillation, which are run through by a countercurrent of steam and liquid in the presence of catalytically active solid under a pressure which ranges between 500 mbar and 50 bar.
