Notes:
The relative hydroxyl radical reaction rate constants from the simulated atmospheric oxidation of selected acetates and other esters have been measured. Reactions were carried out at 297 ± 2 K in 100-liter FEP Teflon®-film bags. The OH radicals were generated from the photolysis of methyl nitrite in pure air. Using a rate constant of 2.63 × 10-11 cm3 molecule-1 s-1 for the reaction of OH radicals with propene, the principal reference organic compound, the rate constants (×1012 cm3 molecule-1 s-1) obtained for the acetates and esters used in this study are: Textn-propyl acetate3.42 ± 0.87n-butyl acetate5.71 ± 0.94n-pentyl acetate7.53 ± 0.482-ethoxyethyl acetate10.56 ± 1.312-ethoxyethyl isobutyrate13.56 ± 2.322-ethoxyethyl methacrylate27.22 ± 2.064-pentene-1-yl acetate43.40 ± 3.853-Ethoxyacrylic acid ethyl ester33.30 ± 1.22Error limits represent 2σ from linear least-squares analysis of data.A linear correlation was observed for a plot of the measured relative rate constants vs. the number of CH2 groups per molecule of the following acetates: methyl acetate, ethyl acetate, n-propyl acetate, butyl acetate, and pentyl acetate. © 1993 John Wiley & Sons, Inc.
