    • A method produces tetrahalosilanes (SiX4) (X=halogen, more particularly Cl, F) from processed rock masses including high-viscosity hydrocarbons and SiO2 and/or silicates, or from the residue masses obtained in the course of such processing. The masses may be heated in a stream of hydrogen halide, and the (SiX4) which forms in the course of this heating is captured or distilled off. The masses may be admixed with hydrofluoric acid (HF) and/or alkali metal fluoride or alkaline earth metal fluoride and with sulfuric acid, and the (SiX4) which forms in the course of the admixing is captured or distilled off.
    • 一种方法是从包括高粘度烃和SiO2和/或硅酸盐的加工岩体或从这种加工过程中获得的残余物质中产生四卤代硅烷(SiX4)(X =卤素,更特别是Cl,F)。 可以在卤化氢流中加热物质,并且在该加热过程中形成的(SiX 4)被捕获或蒸馏掉。 可以将这些物质与氢氟酸(HF)和/或碱金属氟化物或碱土金属氟化物和硫酸混合,并且在混合过程中形成的(SiX 4)被捕获或蒸馏掉。
