The bimolecular rate coefficients k and k were measured using the relative rate technique at (297 ± 3) K and 1 atmosphere total pressure. Values of (2.7 ± 0.7) and (4.0 ± 1.0) × 10−15 cm3 molecule−1 s−1 were observed for k and k, respectively. In addition, the products of 2-butoxyethanol + NO3• and benzyl alcohol + NO3• gas-phase reactions were investigated. Derivatizing agents O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine and N, O-bis (trimethylsilyl)trifluoroacetamide and gas chromatography mass spectrometry (GC/MS) were used to identify the reaction products. For 2-butoxyethanol + NO3• reaction: hydroxyacetaldehyde, 3-hydroxypropanal, 4-hydroxybutanal, butoxyacetaldehyde, and 4-(2-oxoethoxy)butan-2-yl nitrate were the derivatized products observed. For the benzyl alcohol + NO3• reaction: benzaldehyde ((C6H5)C(O)H) was the only derivatized product observed. Negative chemical ionization was used to identify the following nitrate products: [(2-butoxyethoxy)(oxido)amino]oxidanide and benzyl nitrate, for 2-butoxyethanol + NO3• and benzyl alcohol + NO3•, respectively. The elucidation of these products was facilitated by mass spectrometry of the derivatized reaction products coupled with a plausible 2-butoxyethanol or benzyl alcohol + NO3• reaction mechanisms based on previously published volatile organic compound + NO3• gas-phase mechanisms. © 2012 Wiley Periodicals, Inc.* © 2012 Wiley Periodicals, Inc.
