A study of the temperature dependence of the gas-phase reactions of OH radicals and Cl atoms with a series of hydrofluroolefins: 2-fluoropropene (CH3CF=CH2), hexafluoroisobutylene ((CF3)2C=CH2) and (E/Z)-1,2,3,3,3-pentafluoropropene ((E/Z)-CF3CF=CHF) has been performed. The relative-rate technique was used to determine rate coefficients over the temperature range 287-313 K.
This work constitutes the first temperature dependence study of OH radicals and Cl atoms with 2-fluoropropene and (E/Z)-1,2,3,3,3-pentafluoropropene and for the reaction of Cl with hexafluoroisobutylene. Atmospheric implications are discussed with particular reference to the rate coefficients obtained as a function of the temperature.

OH自由基和Cl原子与一系列氢氟烯烃的气相反应的温度依赖性研究:2-氟丙烯(CH 3 CF = CH 2),六氟异丁烯((CF 3)2 C = CH 2)和(已经进行了E / Z)-1,2,3,3,3-五氟丙烯((E / Z)-CF 3 CF = CHF)。相对速率技术用于确定温度范围287-313 K的速率系数。
这项工作构成了OH自由基和Cl原子与2-氟丙烯和(E / Z)-1,2,3,3,3-五氟丙烯以及Cl与六氟异丁烯反应的第一个温度依赖性研究。特别参考获得的速率系数作为温度的函数来讨论大气影响。
