摘要

In a process for preparing alkoxylated amines or alcohols in which a reaction mixture comprising an amine or an alcohol or a mixture of two or more amines and/or alcohols and an alkylene oxide, or a mixture of two or more different alkylene oxides, is reacted in one or more successive reaction steps, at least one of the reaction steps is carried out in the presence of a basic catalyst and, in at least one of the reaction steps, formic acid or a salt of formic acid or a mixture of two or more thereof is present in the reaction mixture or the reaction mixture is admixed with formic acid or a salt of formic acid, or a mixture of two or more thereof, after the alkoxylation is complete. The alkoxylates prepared by the process of the present invention have a light color and a low odor.
