Abstract

La présente invention concerne un procédé de production d'alcools de polyéther, par réaction catalytique de composés à fonction H avec des oxydes d'alkylène. Selon ce procédé, au moins un composé à base de cyanure polymétallique est utilisé en tant que catalyseur. Ce procédé se caractérise en ce que la teneur en impuretés basiques et acides contenue dans la substance de départ et dans les oxydes d'alkylène, qui diminue l'activité du catalyseur, est, au total, inférieure à 100 ppm.
