Abstract: Production of polyether polyols by reaction of diols or polyols with a 2-4C alkylene oxide in the presence of a multi-metal cyanide complex catalyst comprises use of a tall vertical cylindrical reactor with a central stirrer and heat exchange plates arranged in the longitudinal direction of the reactor at an angle, alpha , of 0-70 [deg] in the direction of rotation of the stirrer to the reactor radius. 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 vertical cylindrical reactor with a central stirrer and heat exchanger plates, through which a heat exchange medium flows and which are arranged essentially in the longitudinal direction of the reactor at an angle alpha , of 0-70 [deg] in the direction of rotation of the stirrer to the reactor radius.

Abstract: The invention relates to a method for the production of polyether alcohols b y catalytic addition of at least two alkylene oxides to H-functional starting materials. Said method is characterised in that at least one multi-metal cyanide compound is used as catalyst and in the course of the addition to the starting material at least one oxyalykylene unit is incorporated, during which a common dosing of at least two alkylene oxides occurs, whereby during said common dosing the ratio of the amounts of alkylene oxides to each other is varied.

Abstract: The invention relates to a method for producing polyether polyols by reactin g diols or polyols with ethylene oxide, propylene oxide, butylene oxide or mixtures thereof in the presence of a multimetal cyanide complex catalyst. T he reaction is carried out in a vertical, high cylindrical reactor comprising a discharge nozzle which is situated in the upper reactor area and directed downwards, and by which means the educts and the reaction mixture are supplied; and an outlet which is preferably situated in the lower reactor ar ea and through which the reaction mixture is guided back to the discharge nozzl e by means of a pump and via an equalising reservoir, in an outer circuit. The reactor also comprises a concentric guiding pipe which extends over the enti re length of the reactor with the exception of the reactor ends, and a heat exchanger which is integrated into the annulus.
