摘要：
The invention relates to a process for producing hydrogen-containing chlorosilanes by reducing Si-based deposits of solid material during the operation of a pressurised reactor comprising one or more reaction spaces, wherein at least one organochlorosilane is reacted with hydrogen in at least one of these reaction spaces for at least some of the time, characterized in that at least one of the optionally two or more reaction spaces in which this reaction takes place is supplied with additional HCl for at least some of the time. The additional HCl is preferably produced by hydrodehalogenation of silicon tetrachloride with hydrogen in at least one of the optionally two or more reaction spaces of the reactor.
