The consumption of O atoms and the formation of CO, C//3H//4 (Propyne and propadiene), C//4H//2 (Butadiyne) and other hydrocarbons in the system C//2H//2/O with and without added H atoms has been studied in the temperature range 295-1300 K, p equals 2. 7 mbar. Both the rate of formation and the yield of C//3H//4 in C//2H//2-rich mixtures increases with higher temperature. The rate of C//4H//2 formation increases but the maximum concentration remains constant up to 500 K. The results can be described quantitatively through a slightly modified mechanism of 30 reactions that had been proposed previously for the reaction at room temperature.
