Title (EN) PROCESS FOR THE PREPARATION OF FUNCTIONALIZED POLYOXYALKYLENE POLYOLS
(FR) PROCÉDÉ DE FABRICATION DE POLYOXYALKYLÈNEPOLYOLS FONCTIONNALISÉS
(DE) VERFAHREN ZUR HERSTELLUNG VON FUNKTIONALISIERTEN POLYOXYALKYLENPOLYOLEN
Abstract:
(EN) The invention relates to a process for the preparation of halogen-containing polyoxyalkylene polyols, comprising the step of reacting an alkylene oxide with carbon dioxide in the presence of an H-functional starter compound and a double metal cyanide catalyst, wherein the reaction is further carried out in the presence of an α,β-epoxy-γ-halogen alkane.
(FR) L'invention concerne un procédé de fabrication de polyoxyalkylènepolyols halogénés, comprenant une étape consistant à faire réagir un oxyde d'alkylène avec du dioxyde de carbone en présence d'un composé de départ à fonction H et d'un catalyseur à base de cyanure bimétallique, la réaction étant en outre mise en oeuvre en présence d'un α,β-époxy-γ-halogénoalcane.
(DE) Ein Verfahren zur Herstellung halogenhaltiger Polyoxyalkylenpolyole, umfassend den Schritt der Reaktion eines Alkylenoxids mit Kohlendioxid in Gegenwart einer H-funktionellen Starterverbindung und eines Doppelmetallcyanid-Katalysators, wobei die Reaktion weiterhin in Gegenwart eines α,β-Epoxy-γ-halogenalkans durchgeführt wird.
