Rate and pathways for the reaction of OH with the biogenic p-cymene, an alkylated aromatic

摘要: Aromatics are known to contribute strongly tropospheric formation of ozone, and p-cymene (4-isopropyltoluene) is one only a few biogenic, volatile aromatic hydrocarbons. In spite its symmetry, this molecule (CH3 − φCH(CH3)2) has multitude potential pathways reaction with OH radicals. Addition well-known be the predominating primary step in transformation The addition expected occur preferably at non-occupied position, where four positions available: two equivalent ones ortho methyl group isopropyl group. Furthermore, various C-H bonds (4 10 aliphatic) available for abstraction, leading benzyl-type radicals cases.
