The formation of polycyclic aromatic hydrocarbons (PAHs) during combustion has a substantial impact on environmental pollution and public health. The hydrogen-abstraction-acetylene-addition (HACA) mechanism is expected to be a significant source of larger PAHs containing more than two rings. In this study, the reactions of 1-naphthalenyl and 2-naphthalenyl radicals with acetylene (C2H2) are investigated using VUV photoionization time-of-flight mass spectrometry at 500 to 800 K, 15 to 50 torr, and reaction times up to 10 ms. Our exptl. conditions allow us to probe the Bittner-Howard and modified Frenklach HACA routes, but not routes that require multiple radicals to drive the chem. The kinetic measurements are compared to a temperature-dependent kinetic model constructed using quantum chem. calculations and accounting for chem.-activation and fall-off effects. We measure significant quantities of C14H10 (likely phenanthrene and anthracene), as well as 2-ethynylnaphthalene (C12H8), from the reaction of the 2-naphthalenyl radical with C2H2; these results are consistent with the predictions of the kinetic model and the HACA mechanism, but contradict a previous exptl. study that indicated no C14H10 formation in the 2-naphthalenyl + C2H2 reaction. In the 1-naphthalenyl radical + C2H2 reaction system, the primary product measured is C12H8, consistent with the predicted formation of acenaphthylene via HACA. The present work provides direct exptl. evidence that single-radical HACA can be an important mechanism for the formation of PAHs larger than naphthalene, validating a common assumption in combustion models. The experimental part of the paper was very detailed, including the reaction process of 1-Iodonaphthalene(cas: 90-14-2Synthetic Route of C10H7I)
1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs. Oceanic alkyl iodides are believed to be the principal source of atmospheric iodine.Synthetic Route of C10H7I
