1. The method of separation of dinitroamine from a post-reaction mixture consists in extraction with an organic solvent, followed by product separation. It is characterised in that aqueous solution of post-reaction salt mixture is subjected to multi-stage extraction with an organic solvent, soluble in water, characterised by possibly small water solubility in the solvent itself and containing highly polar groups. Then, the organic extract of dinitroamine salt is subjected to a multi-stage re-extraction into clean water. Dinitroamine salt is obtained by evaporating the water. |
