    Abstract: The invention relates to a method for purifying a gas mixture G-0 containing dinitrogen monoxide, at least comprising: the absorption of the gas mixture G-0 in an organic solvent, followed by; the desorption of a gas mixture G-1 from the loaded organic solvent; the absorption of the gas mixture G-1 in water and subsequently; the desorption of a gas mixture G-2 from the loaded water, and to the use of a purified gas mixture containing dinitrogen monoxide that can be obtained according to a method of the aforementioned type as oxidizing agents for olefins.

    Abstract: A process for the preparation of caprolactam is provided, whereina) a mixture (I) containing 6-aminocapronitrile and water is reacted in the liquid phase, in the presence of a catalyst, to give a mixture (II) containing caprolactam, ammonia, water, high-boiling components and low-boiling components,b) ammonia is then removed from the mixture (II) to give a mixture (III) containing caprolactam, water, high-boiling components and low-boiling components,c) water is then removed from the mixture (III) to give a mixture (IV) containing caprolactam, high-boiling components and low-boiling components, andd) a solid (V) containing caprolactam is then obtained from the mixture (IV) by crystallization, the proportion by weight of caprolactam in the solid (V) being greater than in the mixture (IV).
