| titleOfInvention | Method for manufacturing polyether carbonate polyols |
| abstract | The invention relates to a process for the preparation of polyethercarbonate polyols by addition of alkylene oxides and carbon dioxide to H-functional starter substance in the presence of a double metal cyanide (DMC) catalyst or in the presence of a metal complex catalyst based on the metals zinc and / or cobalt, wherein (γ) alkylene oxide and carbon dioxide are attached to H-functional starter substance in a reactor at a total pressure (absolute) of 5 to 120 bar in the presence of a double metal cyanide catalyst or in the presence of a metal complex catalyst based on the metals zinc and / or cobalt, wherein Reaction mixture containing the polyethercarbonate polyol is obtained (δ) the reaction mixture obtained in step (γ) remaining in the reactor or optionally continuously transferred to a post-reactor at an initial total pressure (absolute) of 5 to 120 bar, wherein in each case by way of an after-reaction, the content of free alkylene oxide is reduced in the reaction mixture , and wherein the total pressure (absolute) during the step (δ) can decrease by up to 50%, and (ζ) the content of volatile constituents of the resulting reaction mixture is thermally reduced at a temperature of 80 ° C to 200 ° C, characterized in that (ε) before step (ζ) the reaction mixture resulting from step (δ) to a total pressure (absolute) of ≦ 2.0 bar, preferably 0.5 bar to 2.0 bar, particularly preferably 0.9 bar to 1, 1 bar and is then left at a temperature of 80 to 180 ° C for a residence time of at least 0.5 h, and after this residence time to the resulting mixture 5 to 100 ppm of component K is added, wherein component K is selected from at least one compound containing a phosphorus-oxygen-hydrogen group. |
