A process is described by which numerous waste or by-product chlorosilane streams can be treated to obtain a granular gel that is easily handleable in further processing steps, shipment, or disposal operations. By hydrolyzing a combined stream with an average SiCl functionality greater than or equal to 2.8 in an aqueous medium at elevated temperature a granular gel is obtained in all cases. The combined stream can be formed by blending several different streams to obtain the desired average SiCl functionality. If the aqueous medium is concentrated hydrogen chloride, the hydrogen chloride generated in the hydrolysis step can be recovered. |
