METODO MELHORADO PARA PRODUCAO DE POLIETER-POLIOIS |
| 摘要 |
The present invention relates to a process for the production of a polyether polyol by polyaddition of an alkylene oxide onto a starter compound containing active hydrogen atoms conducted in the presence of a double metal cyanide catalyst comprising conducting a reaction mixture at least once through a zone which has an energy density of at least 5x10<6 >J/m<3>, wherein the dwell time of the reaction mixture in this zone is at least 10<-6 >seconds per pass. |
