    Abstract: 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.

    Abstract: The invention relates to a method for continually producing 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in liquid phase in the presence of a catalyst. The reaction is carried out in a two-part reactor. In the first part of the reactor, the reaction is carried out with back-mixing until a conversion rate of oxirane II of at least 80 % has been reached. In the second part, the reaction is completed under conditions without back-mixing, the carbon dioxide being guided to the oxirane II in a counterflow throughout the reactor.
