摘要： The invention relates to a method for the continuous production of polyether alcohols by the attachment of alkylene oxides to H-functional starter substances using a DMC catalyst. Said method comprises the following steps: a) production of an intermediate product by the continuous metering of an H-functional starter substance, an alkylene oxide or a mixture of at least two alkylene oxides and the required quantity of a DMC catalyst in a continuous reactor; b) continuous withdrawal of the intermediate product of step a) from the reactor; c) continuous metering of the product obtained in step a), of an alkylene oxide that differs from the product in step a), or a mixture of at least two alkylene oxides that differs from the mixture in step a) and optionally the required quantity of a DMC catalyst in an additional continuous reactor.

摘要： The invention relates to a method for the continuous production of polyether alcohols by reacting alkene oxides with H-functional initiation substances in the presence of DMC catalysts. According to said method: a) a preliminary product and a DMC catalyst are first provided in a reactor, b) alkene oxide is added in such a way that the dosing speed, which is maintained for the continuous operation of the reactor, is reached within 100 to 3000 seconds, c) during or after step b) the initiation substance is added in such a way that the dosing speed, which is maintained for the continuous operation of the reactor, is reached within 5 to 500 seconds, d) once the contents of the reactor have reached the desired level for the continuous operation of said reactor, the product is continuously removed. The initiation substance and alkene oxide are added simultaneously in quantities that enable the level of the contents in the reactor to remain constant and the DMC catalyst is added in such a way that the catalyst concentration required for the continuous operation of the reactor is maintained.

摘要： The invention relates to a method for producing polyetherpolyols by reacting diols or polyols with ethylene oxide, propylene oxide or mixtures thereof in the presence of a multimetal cyanide complex catalyst. The reaction is performed in a vertical, high cylinder reactor with a central mixer-settler and heat exchanger plates through which heat exchanging agents flow. Said plates are arranged in the longitudinal direction of the reactor at an angle α of 0 - 70 ° in the direction of rotation of said mixer-settler in relation to the radius of the reactor.

摘要： The invention relates to multi-metal cyanide compounds, whereby more than 30 % by weight of the primary particles have a plate-like habitus, that is that the length and width of the primary particles are at least three times greater than the thickness of the particles. The invention also relates to the production of said compounds by combining a metal salt with a cyanometallate compound. This method is characterised in that the combination takes place in the presence of at least one surface-active substance.
