Abstract
Rate constants for the gas-phase reaction of hexamethylbenzene (HMB) with O H radicals and H atoms and of 1,3,5-trimethylbenzene (TMB) with H atoms hav e been obtained in a flow system at 295 +/- 2 K and a pressure of 25 mbar H e using MS measurements. Obtained rate constants from a relative rate techn ique are k((OH+HMB)) = (1.13 +/- 0.11) 10(-10), k((H+HMB)) = (5.9 +/- 3.4) 10(-3) and k((H + TMB)) = (4.6 +/- 2.7) 10(-13) cm(3) molecule(-1) s(-1), r espectively.
