在4860 - 6920 K的温度范围内，研究了激波通过稀释的C₂H₂ + Ar混合物时产生的C₂的生成和衰减动力学。C₂的生成动力学与假定的Ar对C₂H₂的简单两步解离基本一致。发现Ar对C₂的解离速率常数为kC₂,Ar = 10⁻(9.21 ± 0.27) exp(–581 ± 59 kJ mol⁻¹/RT) cm³分子⁻¹ s⁻¹。
Kinetics of formation and decay of C2 produced by passing shock waves through dilute C2H2+ Ar mixtures were studied at temperatures in the range 4860–6920 K. The kinetics of formation of C2 were in essential agreement with a postulated simple two-step dissociation of C2H2 by Ar. The rate constant for the dissociation of C2 by Ar was found to be kC2,Ar= 10–(9.21 ± 0.27) exp(–581 ± 59 kJ mol–1/RT) cm3 molecule–1 s–1.
