Process for the recovery of nitroxy compounds from organic solutions and oxidation process

摘要

The present invention relates to a process for the recovery of an organic nitroxy compound from a solution of this nitroxy compound in an organic solvent or a mixture of a water-miscible organic solvent and water, said process comprising the steps of: (a) adjusting the pH of said solution to a value below 4 to generate a nitrosonium ion and the protonated hydroxylamine (b) removing the organic solvent until a residue containing the nitrosonium ion and the protonated hydroxylamine has formed, (c) if necessary, redissolving the residue obtained in water, and (d) neutralizing the resulting aqueous solution to recover the nitroxy compound.
