TL;DR: In this article, a process for the continuous preparation of aqueous alkali metal alkylsiliconate solutions from organotrichlorosilanes via the intermediate organotrialkoxysilane is described.

TL;DR: In this paper, a rectification unit exhibiting an output part and a reinforcing part, where the reinforcing part is operated at a high pressure than the output part, and the heat from the reinforcement part is delivered to the output parts.

TL;DR: The continuous treatment of an aqueous phase produced by hydrolyzing and/or condensing alkoxy-and/or chlorosilanes and separating the resulting silicone resin, where the mixture contains solids, siloxanes, hydrochloric acid and alcohol, comprises: (a) separating solids; (b) extracting siloxane; and (c) separating the alcohol as mentioned in this paper.

Abstract: The invention relates to a continuous process for preparing organylhydrogenchlorosilanes of the general formula (1) RaSiHC13-a (1) from silanes of the general formula (2) RaSiC14-a (2) and silanes of the general formula (3) Ra-1SiHC14-a (3) in a reaction column in the presence of a catalyst which contains at least one fully organically substituted ammonium or phosphonium unit, where R is a hydrocarbon radical having from 1 to 10 carbon atoms and a is 1 or 2, with silane of the general formula (3) being introduced into the reaction column below the point of introduction of the silane of the general formula (2) and the silane of the general formula (1) is taken off at a point in the reaction column which has an elevated concentration of this silane.
