Abstract

Rate constants for reactions of chlorinated methylperoxyl radicals with chlorpromazine (2- chloro-10-[3-(dimethylamino) propyl] phenothiazine), trolox (6-hydroxy-2, 5, 7, 8- tetramethylchroman-2-carboxylic acid), and ascorbate in aqueous alcohol solutions have been measured by pulse radiolysis as a function of temperature, generally between 5 and 75 OC. The rate constants varied between lo6 and lo9 M-'s-', the calculated Arrhenius ...
