ABSTRACT:
A process is described for converting the alkyl-rich disilanes in the residue obtained from the manufacture of alkylhalosilanes to halogen-rich polysilanes with alkyltrihalosilanes and simultaneously converting the alkyltrihalosilanes to dialkyldihalosilanes by reacting the alkyl-rich polysilanes in the residue and the alkyltrihalosilanes at an elevated temperature in the presence of a suitable catalyst and a catalytic amount of a hydrosilane reaction promoter. In a preferred embodiment, the residue containing alkyl-rich disilanes is treated with methyltrichlorosilane at a temperature of about 100.degree. C. to about 250.degree. C. in the presence of aluminum trichloride catalyst and a catalytic amount of methyldichlorosilane.
