    摘要： Polyetherpolyols are prepared by reacting diols or polyols with ethylene oxide, propylene oxide, butylene oxide or a mixture thereof in the presence of a multimetal cyanide complex catalyst by a process which is carried out in a vertical upright cylindrical reactor comprising a jet nozzle which is arranged in the upper reactor region and is directed downward and via which the starting materials and the reaction mixture are fed in, and comprising a take-off, preferably in the lower reactor region, via which the reaction mixture is fed back to the jet nozzle in an external circulation by means of a pump via an equilibration container, comprising a concentric guide tube which extends over the total length of the reactor, except for the reactor ends, and comprising a heat exchanger integrated in the annular space.

    摘要： The invention provides a process for continuously preparing polyether alcohols by adding alkylene oxides to H-functional starter substances using a DMC catalyst, comprising the steps of a) preparing a precursor by continuously metering an H-functional starter substance, an alkylene oxide or a mixture of at least two alkylene oxides and the required amount of DMC catalyst into a continuous reactor, b) continuously withdrawing the precursor from step a) from the reactor, c) continuously metering the product from step a), an alkylene oxide different from that in step a) or a mixture of at least two alkylene oxides different from that in step a) and, if appropriate, the required amount of DMC catalyst into a further continuous reactor.
