最近的地和试验性的研究建议了 alkylamines 的酸硷的反应可以在第二等的喷雾器形成起一个重要作用。我们调查了 ethylamine (EA ) 的异构的化学, diethylamine (DEA ) 和液体 H2SO4 (1 wt%80 wt%) 上的 triethylamine (茶) 。不可逆的反应举起为所有三 alkylamines 被观察。反应举起系数() 与酸增加的 alkylamines,为 DEA 的集中,和价值显得增加比 EA 和茶的稍微快。在不同 alkylamines 的第二等的喷雾器形成的潜在的角色简短被讨论。
Recent field and experimental studies have suggested that acid-base reactions of alkylamines may play an important role in sec- ondary aerosol formation. We investigated the heterogeneous chemistry of ethylamine (EA), diethylamine (DEA) and triethyl- amine (TEA) on liquid H25O4 (1 wt%-80 wt%). Irreversible reactive uptakes were observed for all three alkylamines. The reactive uptake coefficients (γ) of alkylamines increased with the acid concentration, and the γ value for DEA appeared to increase slightly faster than that of EA and TEA. The potential roles in secondary aerosol formation of different alkylamines are briefly discussed.
