The present invention relates to a process for the alkoxylation of organic compounds comprising the reaction of at least one organic compound with at least onealkoxylating agent in the presence of a catalyst system, wherein a polyetheralcohol is obtained. The catalyst system comprises a metallo organic framework mate-rial comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion. Furthermore it relates to polyurethanes or polyurethane foams, which are obtainable by using a prepared polyether alcohol as a starting material.
La présente invention a trait à un procédé d'alcoxylation de composés organiques, consistant à faire réagir au moins un composé organique avec au moins un agent d'alcoxylation en présence d'un système de catalyseur, ce qui permet d'obtenir un alcool de polyéther. Le système de catalyseur comprend un matériau de structure organométallique contenant des pores, au moins un ion métallique et au moins un composé organique bidenté, qui est lié par une liaison de coordination audit ion métallique. De plus, l'invention concerne des polyuréthannes ou des mousses polyuréthanne, que l'on peut obtenir en utilisant, comme produit de départ, un alcool de polyéther préparé.
