Popis:	This paper describes an investigation into the kinetics of the autoxidation of xanthene to xanthylium ion and hydrogen peroxide in a perchloric acid/acetic acid mixture at 20°. Apart from acid catalysis, the reaction also shows the characteristics of a free-radical chain autoxidation. In the mechanism devised to account for the results the key feature is hydrogen abstraction by a protonated peroxy radical with simultaneous production of the stable xanthylium ion
