Improved method for producing 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 10<5 >J/m<3 >and wherein the residence time of the reaction mixture in this zone is at least 10<-6 >seconds per pass. |
