Resumo

The oxidation of olefins С2–С4 in a barrier discharge in the presence of water has been investigated, with the formation of oxygen-containing compounds and various hydrocarbons С1–С5+ of limited and unsaturated structure being observed. The initial olefin’s molecular weight and structure have been found to exert a significant influence on the direction of the reaction. In the ethylene-propylene-butylene series, the proportion of oxygen-containing compounds increases from 28.1, 74.3 and 66.7 wt%, respectively. The oxidation of isobutene isomasalic aldehyde and acetone, with a content of 53 and 21 wt. %, respectively, primarily yields the formation of these compounds. In the case of the oxidation of butene-1 and butene-2, the predominant products are butanol-2, with a yield of up to 26 wt. %.
