Low Energy Electron Attachment by Haloalkanes
Electron attachment process in three halopropanes, CH3CH2CH2Br, CH3CHBrCH3 and CH3CHBrCF3, have been investigated using an electron swarm and electron capture negation mass spectrometry techniques. All compounds attach electrons in dissociative process, and the main product is bromine ion. The rate constants for thermal electron attachment are equal to 1.1·10−1, 1.4·10−12 and 4.1·10−10 cm3molec.−1 s−1 for CH3CH2CH2Br, CH3CHBrCH3 and CH3CHBrCF3, respectively.
