In this scientific work, the results of experiments on the synthesis of N-alkylation products based on local raw materials of
monohydric alcohols and aromatic amines are discussed. The optimal conditions for the synthesis of homologues of aromatic
amines in the presence of a heterogeneous catalyst containing metal oxides and nitrates based on additional elements of group 3d
of the periodic system in the vapor phase have been studied. The structure and structural formula of the synthesized substance
were also analyzed according to the results of the analysis of IR, NMR, NMR spectroscopy. When studying the effect of the
obtained substance on the octane number of AI-80 gasoline in the UIT-85 device, it was found that it increases by 4.9 units. at
1% and 8.5 units. at 2%.
