    摘要: The present invention relates to a process for the preparation of at least one alkoxylate comprising the bringing into contact of an alkylene oxide mixture at least comprising ethylene oxide with at least one starter compound in the presence of at least one double-metal cyanide compound, where, during the induction phase, the sum of inert gas partial pressure and ethylene oxide partial pressure is 1.5 bar to 6.0 bar, to the alkoxylates obtainable by such a process, and to the use of such alkoxylates as emulsifier, foam regulator or as wetting agent for hard surfaces.
