Abstract
The rate constants for the gas-phase reactions between methylethylethe r and hydroxyl radicals (OH) and methylethylether and chlorine atoms ( Cl) have been determined over the temperature range 274-345 K using a relative rate technique. in this range the rate constants Vary little with temperature and average Values of k(MEE+OH) = (6.60(-2.62)(+3.88) ) x 10(-12) cm(3) molecule(-1) s(-1) and k(MEE+Cl) = (34.9 + 6.7) x 10 (-11) cm(3) molecule(-1) s(-1) were obtained. The atmospheric lifetime s of methylethylether have been estimated with respect to removal by O H radicals and CI atoms to be ca. 2 days and ca. 30-40 days, respectiv ely.
