Abstract:
The invention relates to a process for removal of bromine, bromine- and/or iodine-containing silicon compounds from compositions of chlorosilanes containing bromine, bromine- and/or iodine-containing silicon compounds, wherein the composition is subjected to a nonthermal plasma and subsequently the chlorosilanes may be separated from the bromine- and/or iodine-containing compounds present by distillation.

Claim (Index 1):
A process for removal of bromine- or iodine-containing silicon compounds of general formula III\n SiHal 4-n H n  \u2003\u2003(Ill) from compositions of chlorosilanes, wherein the chlorosilanes comprise\n at least one chlorosilane of general formula I\n SiCl 4  \u2003\u2003(I), \n \n polyperchlorosilanes of general formula II \n wherein R 1  is in each case chlorine and wherein m =0 to 100, and\n branched polyperchlorosilanes and/or cyclic polyperchlorosilanes and/or mixtures thereof, \n the process comprising: (i) converting the composition of chlorosilanes into the gaseous state; (ii) subjecting to a nonthermal plasma to obtain a converted composition of chlorosilanes; (iii) distilling the converted composition of chlorosilanes; and (iv) obtaining a composition of chlorosilanes having a reduced content of bromine, bromine- and/or iodine-containing silicon compounds, wherein the silicon tetrachloride of general formula I and/or hexadichlorosilane of formula II where n=0 is subjected to a nonthermal plasma, and the bromine- and/or iodine-containing silicon compounds are halosilanes of general formula III\n SiHal 4-n H a  \u2003\u2003(III), \n wherein at least one Hal is selected from bromine and iodine and further Hal is independently selected from iodine where n=0, 1, 2 or 3.
