Abstract
A process for working up hydrolyzable and/or water-soluble compounds by ping them in water is provided wherein the compounds are fed into the funnel of a rotating cone of water running down into the tip of the cone, with the water being constantly renewed by a supply at the base of the cone. The process is particularly useful for working up mixtures containing silanes and/or chlorosilanes in silicon deposition plants.
