Abstract

The invention relates to the preparation of organic nitrogen compounds, in particular of aminoalkanes, alkyloximes, alkylnitrones or mixtures thereof, which have only one nitrogen-functional group and no alcoholic hydroxyl groups in the molecule, from nitro-containing reaction products of polymers of C.sub.2 -C.sub.6 -olefins with an average degree of polymerization P=5-100 with nitrogen oxides or mixtures of nitrogen oxides and oxygen by hydrogenation of these reaction products. The invention also relates to particular mixtures of such aminoalkanes, alkyloximes and/or alkylnitrones and to individual compounds of these types themselves. The designated products are suitable as additives to fuels and lubricants.
