Abstract (en)

[origin: WO2010130609A1] The invention relates to a method for thermally separating silane mixtures, which contain silanes, selected from alkylchlorosilanes and hydrochlorosilanes, in a distillation apparatus, in which at least part of the heat for heating the distillation apparatus is transferred by vapors of another distillation apparatus, and in which a silane product is obtained having impurities of no more than 200 ppm.
