Abstract
Process for obtaining water-free hydrazine from an aqueous hydrazine solution, characterized in that alkali hydroxide is added to the aqueous hydrazine solution, from this mixture the hydrazine is extracted with an aromatic amine, such as aniline, preferably at room temperature. Higher, such as 60-80º, the extract is separated from the aqueous solution and the extract is separated hydrazine, preferably by distillation.
