Electronic Absorption Spectra of L-ascorbic Acid in Nonaqueous Media

An Electronic spectroscopic study of the self-association of Vitamin C in the nonaqueous phase is reported, pre-sumably for the first time. The oxidation of ascorbic acid in 1,4-dioxane has been studied by UV spectroscopy. The dramatic role of the environment in the stability and identification of the possible intermediates formed in the oxidation of ascorbic acid is shown.
