    Abstract: The invention relates to polyether alcohols that are produced by a ring-opening polymerization of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule to H-functional starting substances. The inventive method is further characterized in that ethylene oxide or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule with an ethylene oxide content of at least 98 %, based on the mixture, is added to the starting substance in an amount of maximally 40 % by weight, based on the weight of the polyether alcohol. At least one alkylene oxide with at least 3 carbon atoms in the molecule or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule and an ethylene oxide content of maximally 20 % by weight, based on the mixture, is added.

    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.
