A flow system has been developed to study relative rate coefficients of hydroxyl radicals reacting with alkanes under conditions relating to tropospheric chemistry. Relative Arrhenius parameters have been measured over the temperature range 243-328 K for pairs of alkanes from a list consisting of n-

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
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 2 K in 100-liter FEP Teflon@-film bags. The OH radicals were generated from the photolysis of methyl nitrite in
Ethers are being increasingly used as motor fuel additives to increase the octane number and to reduce CO emissions. Since their reaction with hydroxyl radicals (OH) is a major loss process for these oxygenated species in the atmosphere, we have conducted a relative rate study of the kinetics of the
The rate constant for the gas-phase reaction of the hydroxyl radical with trifluoroacetic acid has been determined over the temperature range 283-323 K using a relative rate technique. The results provide a value of k( OH+CF,C(O)OH) = 2.O~lO-\*~exp(-l46~500/T)cm~molecule~'s-'basedonk(OH+C~H,)=7.8~lO
