Abstract
Alkyl- or aryl-halogenosilanes are prepared by heating silicon in the presence of copper and calcium, magnesium, beryllium, strontium, barium, germanium, titanium, zirconium or cerium, or p any mixture of these metals, with an alkyl or aryl halide. The reaction gives rise mainly to the mono- and di-alkyl- or aryl-halogenosilanes. The silicon, copper and other metal may be employed in the form of an alloy. The calcium and silicon may be present as calcium silicide. In an example, methyl chloride is passed over a heated mass containing silicon, copper and calcium or titanium to form methyltrichloro- and dimethyldichloro-silane as the main products, and a minor amount of trimethylchlorosilane.ALSO:A contact mass, for reaction by heating with an alkyl or aryl halide to prepare alkyl or aryl halogenosilanes, contains silicon, copper and calcium, magnesium, beryllium, strontium, barium, germanium, titanium. zirconium or cerium or any mixture of these metals, e.g. in the form of an alloy. The calcium and silicon may be present as calcium silicide. The calcium, magnesium, beryllium, strontium, barium, germanium, titanium, zirconium or cerium or any mixture of these metals may be present in a proportion of 1 to 5 per cent. based on the total weight of mass. Preferably, the mass contains silicon, copper and calcium or silicon, copper and titanium. The mass may be prepared by fusing silicon with the metal other than copper, pulverizing the resulting mass and mixing it with copper preferably in the form of a powder and, if desired, a compound volatile at high temperatures such as an ammonium salt, and the powder thus obtained is wetted, moulded and heated in an atmosphere of oxygen free hydrogen. In an example, commercial silicon is fused with 3 per cent. of calcium silicide (containing 33 per cent. calcium) and with 5 per cent. titanium, the proportions being based on the total weight of the mass, the resulting alloys are pulverized and 90 parts of each of the powders are mixed with 10 parts each of copper powder and ammonium bicarbonate. The mixtures thus obtained are wetted, moulded, heated and sintered in a atmosphere of oxygen free hydrogen.
