Abstract:
Separation of chlorosilane mixtures containing boron, arsenic, and/or phosphorus impurities is facilitated by a distillative separation using at least one divided column, with recycle streams to a first column being passed through an external absorbent for the impurities.

Claim (Index 1):
An apparatus for distillative separation of a multicomponent mixture of chlorosilanes and boron, arsenic, and/or phosphorus impurities, comprising two distillation columns materially coupled to one another by vapors from a first distillation column being in communicative connection with a bottom of a second distillation column and bottom draws of the second distillation column being in communicative connection with a reflux section of the first distillation column, wherein an adsorber for removing boron-, phosphorus- and/or arsenic-containing impurities is disposed in the communicative connection between the bottom draws of the second distillation column and the reflux section of the first distillation column and/or in the communicative connection between the bottom draws of the second distillation column and the reflux section of the first distillation column, wherein both distillation columns comprise vertical dividing walls, wherein the second distillation column comprises one or more side draws below a top draw and above the bottom draws.
