Abstract: The invention relates to a base for a mass transfer column, comprising gas through-openings which are distributed over the base (1) and at least one baffle plate (11) for directing the flow of liquid flowing on the base, said base (1) being loadable with a liquid via at least one inlet (3). The base has at least one inlet (3), at least one separating weir (5) which separates the inflowing liquid into two flows, and at least two outlets (12) or at least two inlets (3) and at least one outlet (12) for the liquid. Each flow flows along a flow path (7; 9) to an outlet (12). The invention further relates to a mass transfer column which contains the base and to a use of the base and the mass transfer column.

Abstract: The present invention relates to a method for purifying a gas mixture G-0 containing nitrous oxide, comprising at least the bringing of the gas mixture G-0 into contact with a solvent mixture (I) containing at least 50% by weight of water with respect to the total solvent mixture (I), wherein the pH of the solvent mixture (I) ranges from 3.5 to 8.0, the desorption of a gas mixture G-1 from a composition (A), the bringing into contact of the gas mixture G-1 with a solvent mixture (II) containing at least 50% by weight of water with respect to the total solvent mixture (II), wherein the pH of the solvent mixture (II) ranges from 2.0 to 8.0, and the desorption of a gas mixture G-2 from a composition (B), wherein the pH in each case relates to a measurement with a glass electrode. The invention also relates to the use of gas mixtures obtained by the method according to the invention, as oxidizing agents for olefins.
