Process for the preparation of polyether polyols |
摘要 |
The present invention relates to a process for the production of polyether polyols by polyaddition of alkylene oxides onto starter compounds containing active hydrogen atoms conducted in the presence of a double-metal cyanide catalyst wherein a reaction mixture is guided at least once through a zone which has an energy density of at least 105 J/m3 and wherein the residence time of the reaction mixture in this zone is at least 10-6 seconds per pass. |
