摘要

Process for the preparation of polyether alcohols, by reaction of compounds catalu00ectica h functional alkylene oxides, and polyether alcohol.The invention relates to the process for the production of polyether alcohols by the catalytic reaction of H - functional compounds with alkylene oxides.In which at least one composed of multimetal cyanide is used as the catalyst.The process is characterised by the fact that the total content of alkaline and acidic impurities contained in the starting material and the alkylene oxides and reduce the activity of the catalyst.Is less than 100 ppm.
