Abstract

See full text

A method for producing an organohalosilane, the method comprising: reacting an organic compound comprising a halogen-substituted or unsubstituted aromatic compound with a hydridohalosilane mixture comprising at least two different hydridohalosilanes of formula (I) RnSiHmX4-m-n, where each R is independently C1-C14 hydrocarbyl or C1-C14 hologen-substituted hydrocarbyl, X is fluoro, chloro, bromo, or iodo, n is 0, 1, or 2, m is 1, 2, or 3 and m+n is 1, 2, or 3, in the presence of a catalyst comprising one or more of the elements Sc, Y, Ti, Zr, Hf, Nb, 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, provided that when the at least two different hydridohalosilane comprise a hydridohalosilane of formula (I) where n=0 and m=1 and a hydridohalosilane of formula (I) where n=0 and m=2, the catalyst is 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.
