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: The polyether alcohols production involves converting starting material liquid H-functional compounds with alkyl oxides at ambient temperature in presence of tertiary amines as catalysts. The conversion is performed in presence of 0.25-2 wt.% catalyst relative to weight of the finished polyether alcohols at 90-110 [deg] C, up to hydroxyl number from 500-650 mgKOH/g. 0-1 wt.% catalyst is added relative to weight of the finished polyether alcohols at 100-120 [deg] C up to hydroxyl number from 350-500 mgKOH/g.

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 producing polyether alcohols by the catalytic reaction of H functional compounds with alkylene oxides, whereby at least one multi-metal cyanide compound is used as the catalyst. The method is characterised in that the total content of alkaline and acidic impurities contained in the starting material and the alkylene oxides, which reduce the activity of the catalyst, is less than 100 ppm.
