Summary: | Method for isolating carboxylic acid from an aqueous alkali metal carboxylate-containing side stream, e.g., the aqueous side stream of an organic peroxide production process, with co-production of alkali metal salt, involving adding an acid, or an anhydride, ketene or acid salt, to the aqueous side stream, thereby 5 forming carboxylic acid and alkali metal salt within the aqueous side stream, and separation of the carboxylic acid from the aqueous side stream.
L'invention concerne un procédé d'isolement d'acide carboxylique à partir d'un flux latéral contenant un carboxylate de métal alcalin aqueux, par exemple, le flux latéral aqueux d'un procédé de production de peroxyde organique, avec coproduction de sel de métal alcalin, impliquant l'ajout d'un acide, ou un anhydride, du cétène ou du sel d'acide, au flux latéral aqueux, ce qui permet de former de l'acide carboxylique et un sel de métal alcalin dans le flux latéral aqueux, et de séparer l'acide carboxylique du flux latéral aqueux. |
