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-Cand/or branched hydrocarbons C-Cand/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.

Method for producing high-octane components from olefins from catalytic cracking

The invention discloses a method for selectively introducing carbonyl groups into polymers by oxygenation of double C&#x2550;C bonds of polymers with the aid of nitrous oxide (NO) at a temperature comprised between 50 and 350&#xb0; C. and a pressure of NO of from 0.01 to 100 atmospheres. The introduction of an insignificant amount of C&#x2550;O groups allows one to modify the physico-chemical properties of a polymer, with its molecular weight and molecular-weight distribution preserved. Deeper oxygenation results in controlled cleavage of polymer macromolecules and makes it possible to produce oxygen-containing oligomers having a desired molecular weight.
