Abstract

Phenylacetylene and its chemically active isomer pentalene play an important role in the formation and destruction of polyaromatic hydrocarbons—the main components of the soot microparticles formed during the combustion of fossil fuel, which are the most dangerous anthropogenic aerosol air pollutants for human health. The probable mechanisms of the decay of phenylacetylene and its isomers upon ionization by electron impact are considered. It is shown that the loss of electrons during ionization changes the aromatic/antiaromatic properties of phenylacetylene and its isomers to the opposite properties.

苯乙炔及其衍生物的电子轰击解离

摘要

苯乙炔及其化学活性异构体戊烯在聚芳烃的形成和破坏中起着重要作用。聚芳烃是化石燃料燃烧过程中形成的烟尘微粒的主要成分,是人类健康中最危险的人为气溶胶空气污染物。考虑了通过电子碰撞使苯乙炔及其异构体在电离时衰变的可能机理。结果表明,电离过程中电子的损失使苯乙炔及其异构体的芳族/抗芳族性质改变为相反的性质。
