REACTOR DESIGN FOR REACTING ORGANOCHLOROSILANES AND SILICON TETRACHLORIDE TO OBTAIN HYDROGEN-CONTAINING CHLOROSILANES

摘要

The invention relates to a method for producing hydrogen-containing chlorosilanes while reducing Si-based solid deposits during operation of a pressurized reactor comprising one or more reaction chambers, in at least one of which at least one organochlorosilane is at least partially reacted with hydrogen, characterized in that additional HCl is at least temporarily fed to at least one of the one or more reaction chambers in which said reaction takes place. The additional HCl is preferably produced by hydrodehalogenation of silicon tetrachloride by means of hydrogen in at least one of the one or more reaction chambers of the reactor.
