Abstract: front page image
(DE)Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Polyetherpolyolen, wobei mindestens ein hydroxylgruppenhaltiger Fettsäureester und/ oder mindestens ein hydroxylmodifizierter Fettsäureester unter Zuhilfenahme eines Doppelmetallcyanid-Katalysators in mindestens zwei Verfahrensabschnitten mit jeweils einem Gemisch aus Ethylenoxid und mindestens einem weiteren von Ethylenoxid verschiedenen Alkylenoxid zur Reaktion gebracht wird.
(EN)The invention relates to a method for producing polyether polyols, wherein at least one hydroxyl group-containing fatty acid ester and/or at least one hydroxyl-modified fatty acid ester is caused to react in each of at least two method steps with a mixture of ethylene oxide and at least one further alkylene oxide different from ethylene oxide, using a double metal cyanide catalyst.
(FR)L'invention concerne un procédé pour produire des polyétherpolyols, consistant à faire réagir au moins un ester d'acide gras porteur de groupe hydroxyle et/ou au moins un ester d'acide gras à modification hydroxyle, au cours d'au moins deux étapes, respectivement avec un mélange d'oxyde d'éthylène et d'un d'oxyde d'alkylène différent de l'oxyde d'éthylène, à l'aide d'un catalyseur cyanure métallique double.
