| Abstract: | The scavenger activities of methyl salicylate towards the hydroxyl radical and its reaction mechanism were studied using pulse radiolytic technique and general test method. The apparent rate constants for reactions of hydroxyl radical and methyl salicylate were determined by growth trace of transient absorptions arising from the scavenging of hydroxyl radical by methyl salicylate. Thus methyl salicylate is a good antioxidant. |
