Abstract: The polyether alcohols production involves converting starting material liquid H-functional compounds with alkyl oxides at ambient temperature in presence of tertiary amines as catalysts. The conversion is performed in presence of 0.25-2 wt.% catalyst relative to weight of the finished polyether alcohols at 90-110 [deg] C, up to hydroxyl number from 500-650 mgKOH/g. 0-1 wt.% catalyst is added relative to weight of the finished polyether alcohols at 100-120 [deg] C up to hydroxyl number from 350-500 mgKOH/g.
