    Abstract: A process for the continuous production of 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in the liquid phase in the presence of a catalyst comprises conducting the reaction in a two-part reactor in whose first part the reaction is taken with backmixing to a conversion of not less than 80% of the oxirane II and in whose second part the reaction is completed under nonbackmixing conditions, and passing the carbon dioxide in countercurrent to the oxirane II in the entire reactor.

    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 producing oxalkylated amines or alcohols, whereby a reaction mixture containing 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 are made to react in one or several successive reaction steps. At least one of the steps of the reaction occurs in the presence of a basic catalyst and the reaction mixture in at least one of the reaction steps contains formic acid or a formic acid salt or a mixture of the two or more or the reaction mixture is mixed with formic acid or a formic acid salt or a mixture of the two or more when oxalkylation is finished. The alkoxylates obtained using the inventive method have little natural colour or odour.
