    摘要: A method for separating chlorosilanes from a gaseous mixture which additionally contains hydrogen and hydrogen chloride by washing the gaseous mixture with saturated hydrochloric acid is disclosed. The resulting chlorosilane hydrolysis products can remain in the hydrochloric acid serving as washing liquid, without interfering with the purifying action. The suspended hydrolysis products are easily filtrable, and can be periodically separated from the hydrochloric acid. In a preferred embodiment, the hydrochloric acid is recirculated and injected into the gas stream being washed.
