Title (EN) METHOD OF SYNTHESIZING A DOUBLE METAL CYANIDE CATALYST
(FR) PROCEDE POUR EFFECTUER LA SYNTHESE D'UN CATALYSEUR DE CYANURE METALLIQUE DOUBLE
Abstract: front page image
(EN)An improved method for synthesizing a double metal cyanide (DMC) catalyst combines and sonicates aqueous and non-aqueous solutions of a first metal salt, such as Zn(OAc)2, of a second metal salt, such as CoCl2, and of an alkali metal cyanide, such as NaCN, to synthesize the DMC catalyst, Zn3[Co(CN)6]2. An improved method of producing a polyether polyol uses the DMC catalyst to produce the polyol.
(FR)L'invention concerne un procédé amélioré pour effectuer la synthèse d'un catalyseur de cyanure métallique double (DMC), comprenant l'association et la sonication de solutions aqueuses et non aqueuses d'un premier sel métallique, tels que le Zn(OAc)2, d'un second sel métallique, tel que le CoCl2, et d'un cyanure métallique alcali, tel que le NaCN, pour synthétiser le catalyseur DMC, le Zn3[Co(CN)6]2. L'invention concerne également un procédé amélioré de production d'un polyol de polyéther utilisant le catalyseur DMC pour produire ledit polyol.
