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 3):
An apparatus for distillative separation of a multicomponent mixture comprising chlorosilanes and at least one boron, phosphorus, or arsenic impurity, comprising three distillation columns materially coupled to one another, by vapors from a first distillation column being in communicative connection with a rectifying section of a second distillation column, the rectifying section of the second distillation column being in communicative connection with vapors from a third distillation column, a bottom draw of the first distillation column being in communicative connection with a stripping section of the second distillation column, the stripping section of the second distillation column being in communicative connection with a bottom of the third distillation column, wherein the second distillation column comprises a horizontal dividing wall, the third distillation column comprises one or more side draws below a top draw and above a bottom draw, and disposed in the connection for material coupling of the second distillation column and the third distillation column is an adsorber for removing boron-, phosphorus- or arsenic-containing impurities through which the respective material streams are passed.
