Abstract

Electron attachment to propargyl chloride (HC≡C-CH(2)Cl) was studied in a flowing-afterglow Langmuir-probe apparatus from 305 to 540 K. The sole ion product in this temperature range is Cl(-). Electron attachment is very inefficient, requiring correction for a competing process of electron recombination with molecular cations produced in reaction between Ar(+) and propargyl chloride and subsequent ion-molecule reactions. The electron attachment rate coefficient was measured to be 1.6×10(-10)cm(3) s(-1) at 305 K and increased to 1.1×10(-9)cm(3) s(-1) at 540 K.

摘要

在 305 至 540 K 的流动余辉朗缪尔探针装置中研究了丙炔氯（HC≡C-CH（2）Cl）的电子附加。在这个温度范围内，唯一的离子产物是 Cl（-）。电子附加非常低效，需要对电子与 Ar（+）和丙炔氯之间反应生成的分子阳离子的电子复合竞争过程进行校正，然后进行离子分子反应。在 305 K 时测量的电子附加速率系数为 1.6×10（-10）cm（3）s（-1），在 540 K 时增加到 1.1×10（-9）cm（3）s（-1）。
