Abstract : The relative hydroxyl (OH) reaction rates from the simulated atmospheric oxidation of several acetates and other oxygenated organic compounds have been measured. The OH radical was from the photolysis of methyl nitrite in air. The reaction products of 2-ethoxyethyl acetate with OH identified and quantified and a reaction mechanism is proposed. The measured rate constants (x10(-11)cm(3)molecule(-1)s(-1)) are: 6.77+/-0.50 for trans-4-octene, 1.40+/-0.07 for 4-methyl-2-pentanone, 6.70+/-0.23 for trans-2-heptene, .342+/-0.087 for n-propyl acetate, .571+/-0.094 for n-butyl acetate, 0.753+/-0.048 for n-pentyl acetate, 1.056+/-0.131 for 2-ethoxyethyl acetate, 1.356+/-0.232 for 2-ethoxyethyl isobutyrate, 2.722+/-.206 for 2-ethoxyethyl methacrylate, 4.34+/-.385 4-penten-1-yl acetate, and 3.33+/-0.122 for 3-ethoxyacrylic acid ethyl ester.
