โœฆ Synopsis

The rate constants of the isopropyl acetate, n-propyl acetate, isopropenyl acetate, n-propenyl acetate. n-butyl acetate, and ethyl butyrate reactions with OH radicals were determined in purified air under atmospheric conditions, at 750 torr and (295 ? 2 ) K. A relative rate experimental method was used, n-heptane, n-octane, and n-nonane were the reference compounds, with, respectively. rate constants for the reaction with OH of 7 12 X 8 42 X and 9 70 X molecule -' cm3 s-' : isopropyl acetate, (3.12 5 0.291, n-propyl acetate, (1.97 5 0.24); isopropenyl acetate, (62 53 2 1 24); n-propenyl acetate, (24 57 ? 0.24); n-butyl acetate, (3.29 2 0.35). and ethyl butyrate.

Some relative rate experiments have been carried out at room temperature and at atmospheric pressure. This concerns the OH-oxidation of some oxygenated volatile organic compounds including methanol (k 1 ), ethanol (k 2 ), MTBE (k 3 ), ethyl acetate (k 4 ), n-propyl acetate (k 5 ), isopropyl acetate

CF 3 CF 2 CH 2 OH is a new chlorofluorocarbon (CFC) alternative. However, there are few data about its atmospheric fate. The kinetics of its atmospheric oxidation, the OH radical reaction of CF 3 CF 2 CH 2 OH, has been investigated in a 2-liter Pyrex reactor in the temperature range of 298 ฯณ 356 K u
