In the absence of another H-atom donating source in the reaction mixture, such products´ generation suggests in situ fragmentation of a fraction of parent molecules to C<sub>1</sub> and C<sub>2</sub> stages, followed by preferential reactions of these fragments with H-atoms freed along. Simultaneous formation of nonvolatile deposits containing diverse oxygenated and nonoxygenated long-chained aliphatic and cyclic compounds also occurred due to the remaining fraction´s reactions, including some with the unreacted parent and the adsorbed moisture on dielectric surfaces. The presence of 4% O<sub>2</sub> in the gas mixture induced a significant decrease in gas-phase hydrocarbons´ yields in addition to a change in the nonvolatile products´ nature.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>discharges (electric); free radical reactions; organic compounds; plasma chemistry; plasma sources; C1 hydrocarbons; C2 hydrocarbons; DBD assisted cyclohexane transformation; H-atom donating source; acetylene; aliphatic compounds; argon DBD; cyclic compounds; dielectric barrier discharge; ethylene; in situ fragmentation; methane; nonoxygenated long chained compounds; nonvolatile deposits; oxygenated long chained compounds; parent molecules; preferential reactions; reaction mixture; Argon; Degradation; Dielectrics; Discharges (electric); Frequency measurement; Hydrocarbons; Surface treatment; <formula formulatype=$ $hbox{C}_{1}{-}hbox{C}_{2}$ hydrocarbons; Cyclohexane; dielectric barrier discharge (DBD); free-radical reactions; gas chromatograph;
