quinone-hydroquinone organic systemaqueous magnesium perchlorate electrolytecyclic voltammetric investigationsThis paper reports cyclic voltammetric investigations of the quinone—hydroquinone redox system in aqueous magnesium perchlorate medium containing different concentrations of p -benzoquinone. The studies have ...
The quinone/hydroquinone sesquiterpenes of drimane or rearranged drimane skeletons constitute a wide and diverse group of secondary metabolites of mixed biogenesis. These compounds are mainly of marine origin and their interest is not only for the variety of isolated structure but for the interesting bi...

The properties of graphite electrodes modified by the quinone-hydroquinone systemQuinoneHydroquinoneSolubility ProductGraphite ElectrodePure SubstanceThe standard states of quinone and hydroquinone were selected to be those of pure substances, which allowed us to introduce the solubility product of quinhydrone...
Redox polymers based upon the hydroquinone–quinone redox system are prepared by the addition of hydroquinone and hydroquinone derivatives to preformed polystyrene matrices. Conventional gel and macroreticular styrene–divinylbenzene copolymers were chloromethylated with chloromethyl ether by using a Friedel-...

The contents of α-tocopherolhydroquinone (TQH2), α-tocopherolquinone (TQ) and α-tocopherol (Toc) in isolated rat hepatocytes and liver homogenates were determined by HPLC under anaerobic conditions, because TQH2 easily autoxidizes to TQ under aerobic conditions. The viable hepatocytes were used...
