The invention relates to the field of petrochemistry, and specifically to a method for synthesizing high-octane oxygen containing components of motor fuel. The objects of the invention consist in variants of a method for synthesizing high-octane oxygen-containing components of motor fuel from olefin-containing gas mixtures via oxidative non-catalytic conversions using nitrous oxide, and the subsequent condensation and hydrogenation of the produced oxygenates using heterogeneous catalysts. The high-octane components according to the proposed method consist in a mixture of carbonyl compounds (ketones, aldehydes, hydroxy ketones, hydroxy aldehydes) C.sub.2-C.sub.9 and/or branched hydrocarbons C.sub.5-C.sub.9 and/or alcohols in different ratios. Depending on the production method variant, the octane number of a mixture of the proposed high-octane components consists in a value between 100 and 130 RON. The technical result consists in broadening the resource base for the production of high-octane gasolines and of a variety of environmentally-friendly high-octane additives.
