在自制的烟雾室中，在（300±1）K和1.01 × 105Pa条件下进行了一系列实验，模拟甲基硫乙酯（EMS）与NOx的光化学反应。结果表明，初始浓度越高，模拟反应生成的臭氧越多。结果表明，光强在评价EMS的臭氧形成潜力中起着非常重要的作用。使用d（O3-NO）和IR（增量反应性）参数来量化EMS对臭氧形成的影响。本文得到的5种模拟反应的最大IR值分别为1.55 × 10−2、0.99 × 10−21.36 × 10−2、2.47 × 10−2和1.65 × 10−2。我们在这里得到的结果与我们之前得到的过氧化二叔丁基和乙炔的结果比较表明，EMS对臭氧形成的潜在反应性处于相对较低的水平。
A series of experiments were conducted in a self-made smog chamber at (300 ± 1) K and 1.01 × 105Pa to simulate the photochemical reaction of ethyl methyl sulfide (EMS) and NOx. The results showed that the higher the initial concentration of EMS, the more ozone was generated in the simulative reactions. It was found that the light intensity plays a very important role in the evaluation of ozone formation potential for EMS. The parameters of d(O3-NO) and IR (incremental reactivity) were used to quantify the potential of EMS on ozone formation. The obtained maximum IR values in this article for the five simulative reactions were 1.55 × 10−2, 0.99 × 10−21.36 × 10−2, 2.47 × 10−2, and 1.65 × 10−2, respectively. A comparison between the results we obtained here and the results we obtained previously for di-tert-butyl peroxide and acetylene showed that the potential reactivity of EMS on ozone formation was at a relatively low level.
