利用180-L Teflon气袋,采用相对速率方法测定了298K,1.013×105 Pa条件下·OH自由基与6种还原态硫化物在空气、氮气和氧气体系下的反应速率常数.所得结果与文献值进行了比较,并讨论了氧气对速率常数的影响.
The reaction rate constants of · OH and 6 kinds of reduced sulfides in air, nitrogen and oxygen at 298K and 1.013 × 105 Pa were measured by relative velocity method in a 180-L Teflon air bag. The obtained results are in good agreement with the literature The values were compared and the effect of oxygen on the rate constant was discussed.
