| titleOfInvention | Activation method of double metal cyanide catalyst for the production of polyether polyols |
| abstract | The present invention (α) (α1) DMC catalyst and one or more H-functional starting compounds into the reactor, (α2) an inert gas, an inert gas / carbon dioxide mixture or carbon dioxide is passed through the reactor at a temperature of 50 to 200 ° C. and at the same time a reduced pressure (absolute pressure) of 10 mbar to 800 mbar is established in the reactor by removal of the inert gas or carbon dioxide, (β) under the atmosphere of an inert gas / carbon dioxide mixture or under a carbon dioxide atmosphere, a partial amount of one or more alkylene oxides (based on the total amount of alkylene oxides used in steps (β) and (γ)) is 50 to Add to the mixture from step (α) at a temperature of 200 ° C., (γ) characterized in that metered addition of at least one alkylene oxide and carbon dioxide to the mixture resulting from step (β), To a process for preparing polyethercarbonate polyols from at least one H-functional starting compound, at least one alkylene oxide and carbon dioxide in the presence of a double metal cyanide (DMC) catalyst and to a method of activating a double metal cyanide catalyst It is about. |
