REACTIONS OF ATOMIC OXYGEN WITH ACETYLENE (I), KINETICS AND MECHANISMS
Abstract
The room temperature reaction of acetylene with atomic oxygen was studied in a moderately fast flow system. The course of the reaction was followed using both a Mass Spectrometer and a photometric method. The major products of the reaction were Co and H. Large amounts of atomic H were also observed. The rate of the overall reaction is determined by the first initial step in which atomic O adds to acetylene to yield an excited complex which then undergoes unimolecular decomposition to give triplet methylene. The rate constant for this initial reaction was measured, at room temperature, as (8.9 = 2.8)x 10 to the -14th power cc/mol sec. The activation energy was less than 1 kcal./mol. Experiments with acetylene-d2 established the reactions which constitute the major pathway by which triplet methylene is consumed.
