Abstract
A method for producing an organohalosilanes comprising reacting an organic compound comprising a halogen-substituted or unsubstituted alkane, a halogen-substituted or unsubstituted alkene, or an aromatic compound and at least one hydridohalosilane of formula RnSiHmX4-m-n, wherein each R is independently C-1-C-14 hydrocarbyl or C-1-C-14 halogen-substituted hydrocarbyl, X is fluoro, chloro, bromo, or iodo, n is 0, 1, or 2, m is 1, 2 or 3, and m+n=1, 2 or 3, in the presence of a heterogeneous catalyst comprising an oxide of one or more of the elements Sc, Y, Ti, Zr, Hf, B, Al, Ga, In, C, Si, Ge, Sn, or Pb, at a temperature greater than 100° C., and at a pressure of at least 690 kPa, to produce a crude reaction product comprising the organohalosilane.
