| titleOfInvention | Process for the reprocessing-free production of long-chain polyether polyols |
| abstract | The invention relates to a process for the reprocessing-free production of long-chain polyether polyols, in which first by catalysis with perfluoroalkylsulfonates of metals of group III A of the periodic table of the elements (in accordance with the IUPAC Convention of 1970) from low molecular weight starters by reaction with alkylene oxides at reaction temperatures of 80 to 200 ° C. and catalyst concentrations of 5 to 200 ppm of oligomeric, alkoxylated starting compounds with molecular weights between 200 and 1000 are obtained, which are then processed without workup and catalyst removal by means of highly active DMC catalysts at a catalyst concentration of 30 ppm or less, based on the amount of the polyether polyol to be produced , by reaction with alkylene oxides to form higher molecular weight, long-chain polyether polyols. |
