| Abstract | A bimolecular rate constant, k(OH+Benzyl alcohol), of (28 +/- 7) x 10 (12) cm(3) molecule (1) s(-1) was measured using the relative rate technique for the reaction of the hydroxyl radical (OH) with benzyl alcohol, at (297 +/- 3)K and 1 atm total pressure. Additionally, an upper limit of the bimolecular rate constant, k(O3+Benzyl alcohol), of approximately 6 x 10(-19)cm(3) molecule(-1) s (1) was determined by monitoring the decrease in benzyl alcohol concentration overtime in an excess of ozone (O-3). To more clearly define part of benzyl alcohol's indoor environment degradation mechanism, the products of the benzyl alcohol + OH were also investigated. The derivatizing agents O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine (PFBHA) and N,O-bis(trimethylsilyl) tr fluoroacetamide (BSTFA) were used to positively identify benzaldehyde, glyoxal and 4-oxopentanal as benzyl alcohol/OH reaction products. The elucidation of other reaction products was facilitated by mass spectrometry of the derivatized reaction products coupled with plausible benzyl alcohol/OH reaction mechanisms based on previously published volatile organic compound/OH gas-phase reaction mechanisms.
