Abstract

A process for obtaining hexachlorodisilane and uses for the same. The process includes contacting at least one partially hydrogenated chlorodisilane of general formula HxSi2Cl(6-x) where x is from 1 to 5 in the liquid state with a solid non-functionalized adsorber material that is selected from the group comprising silicates, aluminosilicates, organic polymer and/or combinations thereof. The process also includes optionally separating the hexachlorodisilane and/or optionally separating the adsorber material.
