Title
(EN) PROCESS FOR THE BENIGN DIRECT FIXATION AND CONVERSION OF NITROGEN OXIDES
(FR) PROCEDE DE FIXATION DIRECTE BENIGNE ET DE CONVERSION D'OXYDES D'AZOTE
Abstract
(EN)
A direct fixation of NO2 and N2O4 at room temperature and atmospheric pressure is described using bis(diorganoamino)magnesium compounds formed from reactions between donor-solvent free diorganomagnesium compounds and primary or secondary amines, yielding new compositions of matter having the general formulas [(R2N)i(R2NNxOy)jMg]m and [(R2N)i(R2NNxOy)j(NxOy)kMg]m. Methods are also described to convert these new compositions of matter into useful organic compounds and nitrogen gas.
(FR)
L'invention porte sur une fixation directe de NO2 et N2O4 dans des conditions de température et de pression atmosphérique ambiantes, au moyen de composés de bis(diorganoamino)magnésium formés par réaction entre des composés de diorganomagnésium exempts de solvant donneur d'hydrogène et des amines primaires ou secondaires. Les composés de l'invention donnent de nouvelles compositions de matière des formules générales [(R2N)i(R2NNxOy)jMg]m et [(R2N)i(R2NNxOy)j(NxOy)kMg]m. L'invention porte également sur des procédés de conversion de ces nouvelles compositions de matière en composés organiques et azote gazeux utiles.
