Abstract:
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.
