Process for the separation of organic nitrosonium and/or hydroxylamine compounds by means of cation exchange resins and recovery and oxidation processes based thereon

摘要

A process for the separation of a secondary organic nitrosonium compound and/or a secondary organic hydroxylamine compound from an acidic aqueous medium containing them in dissolved form, includes the step of bringing into contact said acidic aqueous medium with a cation exchange resin. The process is used in a process for the recovery of secondary organic nitroxy compounds from an aqueous medium containing the nitroxy compound and oxidation processes for hydroxy compounds.
