Abstract:
1. Process for production of trisilylamine in the liquid phase, which process comprises initially charging monochlorosilane (A or A′) to a reactor ( passing ammonia (B) into the reactor in the form of a solution in the solvent (H), performing the reaction in reactor ( subsequently passing the resultant product mixture from reactor ( passing the filtrate from the filter unit ( excess monochlorosilane (A′) being distilled in distillation column ( removing gaseous substances (D) from the distillation column ( conveying the bottoms (E) into the distillation column ( the product trisilylamine (G) being distilled in the distillation column ( conveying the bottoms (F) into the distillation column ( the solvent (H) being distilled in distillation column ( exporting higher boilers via the bottoms (I).
