METHOD FOR PRODUCING POLYETHER ALCOHOLS

The invention relates to a method for producing polyether alcohols by the catalytic reaction of H functional compounds with alkylene oxides, whereby at least one multi-metal cyanide compound is used as the catalyst. The method is characterised in that the total content of alkaline and acidic impurit...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing polyether alcohols by the catalytic reaction of H functional compounds with alkylene oxides, whereby at least one multi-metal cyanide compound is used as the catalyst. The method is characterised in that the total content of alkaline and acidic impurities contained in the starting material and the alkylene oxides, which reduce the activity of the catalyst, is less than 100 ppm.
