Destruction of Acetylene in Flames with Oxygen

Abstract
The rate of consumption of acetylene in premixed flames is compared with the simultaneous rates of disappearance of oxygen, supposed to react by H+O2⇄OH+O, and appearance of carbon dioxide, OH+CO→CO2+H. The comparisons are consistent with a consumption of acetylene by O atoms but not by H, OH, or O2. The destruction probably involves a direct attack of O on carbon in acetylene with a rate constant of 1 to 2×1013 cm3 mole—1 sec—1 and little temperature dependence.
