Abstract
The reactivity of natural unsubstituted di- and trihydroxybenzenes in the reaction with a stable free radical 2,2-diphenyl-1-picrylhydrazyl in a mixed solvent water-dimethyl sulfoxide (2:1) was investigated. Kinetic and stoichiometric parameters of the studied reaction were estimated. In the water environment the studied hydroxybenzenes were found to dissociate to form ions, which reacted rapidly with the radical by the mechanism of single electron transfer with subsequent adding a proton. The corresponding rate constants were calculated taking into account the concentration of the ionized form of phenol.
