Abstract: The invention relates to a column for separating mixtures containing at least three substances. Said column comprises an outer enclosure which delimits the inner area of the column, at least one column lid (5) and several subchambers (3, 4) which extend over a section of the longitudinal extension of the column and open into the inner area of the column at one end. One subchamber is configured in the form of a feed chamber (3) to which the mixture to be separated is delivered. The column also comprises at least one recombination chamber (8) which adjoins the opening of at least two subchambers (3, 4) leading into the inner area of the column. The mixture to be separated is delivered to the feed chamber at a point that is set apart from the open of said feed chamber (3), in such a way that the feed chamber forms a concentrating column (3a) in the section adjoining the delivery point on one side and forms a column stripper in the section (3b) adjoining the delivery point on the other side. As a result, complex mixtures can be separated into pure fractions and the invention is simpler than series-connected columns in terms of equipment and energy.

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.
