摘要： Proposal is given of a method for the preparation of an organopolysiloxane highly freed from any trace amount of the residue of sulfuric acid or fuming sulfuric acid by the siloxane rearrangement reaction of organosiloxane oligomers into equilibirium by using the acid catalyst. The inventive method comprises subjecting the reaction mixture, after completion of the reaction but before the conventional step of washing with a large volume of water to remove the acid residue, to a hydrolysis reaction of the acid residue bonded to the organopolysiloxane molecules with admixture of a limited amount of water and separating the mixture into aqueous and organopolysiloxane phases to discard the acid-containing aqueous phase.

摘要： For the continuous hydrolysis of organochlorosilane, a reaction system comprising at least three stages of hydrolysis is used. Each stage includes a reactor and a phase separator wherein hydrolysis is effected to form a hydrolysis mixture which is separated into a hydrolyzate and a hydrogen chloride-containing aqueous medium. The separated aqueous medium is circulated to the reactor. The hydrolyzate is conveyed to the reactor of the subsequent stage. The organochlorosilane is fed into the first stage reactor, the aqueous medium containing an amount of water corresponding to the consumption in one stage is fed into one stage reactor from the subsequent stage, and an amount of water corresponding to the consumption in the overall reaction system is fed in the last stage. Then the entire amount of hydrogen chloride generated in multiple stages of hydrolysis is recovered as anhydrous hydrogen chloride from the first stage. The entire amount of the aqueous media separated in the phase separators is retained in the reaction system.
摘要翻译：对于有机氯硅烷的连续水解，使用包含至少三个水解阶段的反应体系。每个阶段包括反应器和相分离器，其中进行水解以形成分离成水解产物和含氯化氢的水性介质的水解混合物。将分离的水性介质循环至反应器。水解产物被输送到后续阶段的反应器。将有机氯硅烷进料到第一阶段反应器中，将含有相当于一步消耗量的水的含水介质从后续阶段进料到一级反应器中，并且一定量的水对应于整个反应体系中的消耗在最后阶段喂养。然后从第一阶段以多级水解产生的全部量的氯化氢作为无水氯化氢回收。在相分离器中分离的水性介质的全部量保留在反应体系中。
