Abstract: The mechanism of oxidation of the ascorbic
acid by hydrogen peroxide have been investigated
by using the 6311++G(d,p) basis set of the density
functional theory (DFT) method at the B3LYP level
of theory. Thermodynamic and kinetic characteristics
of proton transfer from ascorbic acid molecule to hydrogen
peroxide as well as the equilibrium constants
were calculated for the related processes. Different
solvents and the reaction mixtures (reactant and transition
state) were considered using the DFT solvation
calculations. The quantum theory of atoms in molecules
(QTAIM) analysis has been applied for the
study of the interactions and the electron density at
the BCP of the O-H in the solution which was more
than gas phase at the TSs.
