  • Process for preparing hydridosilanes
    Patent number: 9011812
    Abstract: The present invention relates to a process for preparing hydridosilanes from halosilanes, in which a) i) at least one halosilane of the generic formula SinX2n+2 (where n?3 and X=F, Cl, Br and/or I) and ii) at least one catalyst are converted to form a mixture comprising at least one halosilane of the generic formula SimX2m+2 (where m>n and X=F, Cl, Br and/or I) and SiX4 (where X=F, Cl, Br and/or I), and b) the at least one halosilane of the generic formula SimX2m+2 is hydrogenated to form a hydridosilane of the generic formula SimH2m+2, the hydridosilane of the generic formula SimH2m+2 is separated from partially halogenated hydridosilanes of the general formula SimH(2m+2?y)Xy (where 1<y<2m+1), and the separated partially halogenated hydridosilanes of the general formula SimH(2m+2?y)Xy (where 1<y<2m+1) are hydrogenated again.
