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 reactions of OH radicals with a series of ethers. Experiments were performed under simulated atmospheric conditions. Using rate constants for the reaction of OH radicals with n-butane and diethyl ether, the rate constants were derived for all the ethers studied. The implications of these results for the atmospheric chemistry of ethers are discussed.
