  • Kinetics and Mechanism of the Thermal Gas-Phase Reaction between NO<sub>2</sub> and Perfluoropropene

    Abstract

    The reaction of NO2 with perfluoropropene (C3F6) has been studied at 413.1, 421.0 and 432.8K, using a conventional static system. The initial pressure of NO2 was varied between 43.6 and 204.0Torr and that of C3F6 between 10.2 and 108.5Torr. Several experiments were made adding CF4, varying its pressure from 338.8 to 433.6Torr. Four products were observed: NO and perfluoropropene oxide (PFPO), formed in equivalent amounts, CF3CF(NO2)CF2NO2 and CF3C(O)CF2NO2. The relation R=[PFPO]/([CF3CF(NO2)CF2NO2] + [CF3C(O)CF2NO2]) increases with temperature and decreases as the concentration of NO2 and the total pressure M increase. The yields of PFPO, based on the amount of C3F6 consumed, varied between 63 and 89% and those of CF3CF(NO2)CF2NO2 between 0.33 and 0.08%. Increasing the temperature, the yields of CF3C(O)CF2NO2 decreased from 0.04 to 0.01%. The reaction is homogenous and the consumption rate of perfluoropropene, −d[C3F6]/dt= k 1[C3F6][NO2], is independent of the total pressure. The following mechanism is postulated to explain the experimental results: 1) C3F6 + NO2 → CF3CFCF2NO2, 2) CF3CFCF2NO2 → PFPO+NO, 3) CF3CFCF2NO2 + NO2+M → CF3CF(NO2)CF2NO2+M, 4) CF3CFCF2NO2 + NO2 → CF3C(O)CF2NO2+FNO. k 1=(4.57±1.4)×106exp(−(15.44±1.2) kcal mol−1/RT) dm3mol−1s−1. The value of k 2, the rate constant for the unimolecular dissociation of the radical CF3CFCF2NO2, was found to be of order of 1014s−1.

    摘要:研究了NO2与全氟丙烯(C3F6)在413.1、421.0和432.8K下的反应,采用传统的静态系统。NO2的初始压力在43.6至204.0Torr之间变化,C3F6的压力在10.2至108.5Torr之间变化。进行了几次实验,添加了CF4,将其压力从338.8至433.6Torr之间变化。观察到四种产物:NO和全氟丙烯氧化物(PFPO),它们的数量相等,CF3CF(NO2)CF2NO2和CF3C(O)CF2NO2。关系R=[PFPO]/([CF3CF(NO2)CF2NO2]+[CF3C(O)CF2NO2])随着温度的升高而增加,随着NO2和总压力M的浓度增加而减小。基于消耗的C3F6的数量,PFPO的产率在63%至89%之间变化,CF3CF(NO2)CF2NO2的产率在0.33%至0.08%之间变化。随着温度的升高,CF3C(O)CF2NO2的产率从0.04降至0.01%。反应是均相的,全氟丙烯的消耗速率,−d[C3F6]/dt=k1[C3F6][NO2],独立于总压力。提出以下机理来解释实验结果:1)C3F6+NO2→CF3CFCF2NO2,2)CF3CFCF2NO2→PFPO+NO,3)CF3CFCF2NO2+NO2+M→CF3CF(NO2)CF2NO2+M,4)CF3CFCF2NO2+NO2→CF3C(O)CF2NO2+FNO。k1=(4.57±1.4)×106exp(−(15.44±1.2) kcal mol−1/RT) dm3mol−1s−1。发现k2,自由基CF3CFCF2NO2的单分子解离速率常数,约为1014s−1

    )O2CF2C(O)CF3 free radicals upon the UV irradiation of nitropentafluoroacetone (1) in toluene and mesitylene is established by ESR. The most likely cause of their formation is the one-electron oxidation of the solvents by photoexcited1 followed by decay of the radical anion formed from1 with the expulsion of an NO2 anion and attachment of the radical to a molecule of original1. The irradiation of 1 in triethylsilane
    ESR 建立了在硝基五氟丙酮 (1) 在甲苯和均三甲苯中进行紫外线照射后形成 CF3C(O)CF2N(O.)O2CF2C(O)CF3 自由基。它们形成的最可能原因是溶剂被光激发 1 的单电子氧化,然后是由 1 形成的自由基阴离子衰变,排出 NO2 阴离子并将自由基附着到原始分子 1 上。1 在三乙基硅烷中的辐照导致氟离子的消除和 CF3COCFN(O-)O' 自由基的固定。戊烷中的酮 1 的紫外线照射导致从溶剂中提取氢原子并形成 CF3COCF2N(OH)O' 自由基。
