simulation chamber. NO(3) was produced inside the reactor by thermal decomposition of N(2)O(5) previously added to the air-VOC mixture, and concentrations were monitored using FTIR spectrometry. All the kinetic experiments were carried out by relative rate technique using isoprene as reference compound, leading to the rate constants k(1) = (7.2 +/- 1.5) x 10(-13), k(2) = (13.1 +/- 2.7) x 10(-13), k(3) = (13
在对流层条件下(大气压和T = 293 +/- 3 K)在LI
SA室内模拟室内研究了甲基,乙基,丙基和丁基
乙烯基醚的NO(3)氧化。通过预先分解到空气-VOC混合物中的N(2)O(5)进行热分解,在反应器内部产生NO(3),并使用FTIR光谱法监测其浓度。所有动力学实验均以相对速率技术进行,使用
异戊二烯作为参比化合物,得出速率常数k(1)=(7.2 +/- 1.5)x 10(-13),k(2)=(13.1 + / -2.7)x 10(-13),k(3)=(13.3 +/- 3.0)x 10(-13)和k(4)=(17.0 +/- 3.7)x 10(-13)cm( 3)分别为甲基,乙基,丙基和丁基
乙烯基醚的分子(-1)s(-1)。已经确定了主要的氧化产物,例如
甲醛和甲基,乙基,丙基,和丁基
甲酸酯。氧化产物的产率接近50%。还检测到氧化的
硝酸盐和
