Abstract: 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.

Abstract: According to the inventive method, the polyurethane foams are produced by reacting isocyanates with compounds that react with isocyanates in the presence of foaming agents and optionally, catalysts, additives and/or auxiliary agents. The method is characterised in that the reaction is carried out in the presence of at least one of the following compounds (i): alpha , beta -unsaturated carboxylic acid, alpha , beta -unsaturated carboxylic acid derivative, alpha , beta -unsaturated ketone and or alpha , beta -unsaturated aldehyde.

Abstract: A process for the preparation of polyetherpolyols 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 is proposed, the reaction being carried out in a stirred kettle reactor and the reaction mixture being circulated via an external heat exchanger by means of a pump.

Abstract: Production of polyether polyols comprises use of a multi-metal cyanide complex catalyst in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed and an outlet, preferably in the lower portion of the reactor to recirculate the reaction mixture via an external circuit and equalizing reservoir. A process for the production of polyether polyols (I) by reaction of diols or polyols with ethylene oxide, propylene oxide and/or butylene oxide in the presence of a multi-metal cyanide complex catalyst (II) comprises carrying out the reaction in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed, and an outlet, preferably in the lower portion of the reactor, through which the reaction mixture is fed by means of a pump through an external circuit via an equalizing reservoir to the spray nozzle. The external circuit comprises a concentric pipe stretching the entire length of the reactor excluding the reactor ends and contains a heat exchanger integrated within the annulus.

Abstract: In a process for preparing polyether alcohols by catalytic addition of at least two alkylene oxides onto H-functional initiator substances, at least one multimetal cyanide compound is used as catalyst and the addition of the alkylene oxides onto the initiator substance includes incorporation of at least one oxyalkylene block during whose formation at least two alkylene oxides are metered in together and the ratio of the alkylene oxides to one another in the mixture is changed during the joint introduction.
