A continuous process for the ethoxylation and propoxylation of fatty alcohols, alkyl phenols and fatty acids, based on the flow principle, is described. The short-time process developed on a pilot-plant scale leads to a high space-time yield in the presence of alkaline catalysts with complete conversion of the alkylene oxides at extremely short residence times of 10–80 sec. The products are of excellent quality.
