thermodynamic study of an effective catalytic system, hydrogen peroxide and methyltrioxorhenium
Authors
abstract
the thermodynamic of the known and very effective catalytic system, hydrogen peroxide (h2o2) and methyltrioxorhenium (mto) is studied in different solvents using uv-visible spectroscopic method. the thermodynamic parameters (δg, δh and δs) for two equilibrium reactions, mto + h2o2 ⇌ a + h2o and a + h2o2 ⇌ b.h2o (a, [mere(o)2(o2)]; b.h2o, [mere(oh2)(o)(o2)2]), are determined. the obtained free energies of the reactions depend on dielectric constants of solvent, which are explained by onsager’s reaction field theory.

full textSelective oxidation reactions of natural compounds with hydrogen peroxide mediated by methyltrioxorhenium.
We have investigated the oxidative behaviour of natural compounds such as methyl abietate (1), farnesyl acetate (2), α-ionone (3), β-ionone (4), methyl linolelaidate (5), methyl linolenate (6) and bergamottin (7) with the oxidant system methyltrioxo-rhenium/ H2O2/pyridine. The reactions, performed in CH2Cl2/H2O at 25 °C, have shown good regio- and stereoselectivity. The oxidation products were ...
full textHydrogen Peroxide as an Effective Disinfectant for Pasteurella multocida
Pasteurella multocida (P. multocida) infections vary widely, from local infections resulting from animal bites and scratches to general infections. As of yet, no vaccine against P. multocida has been developed, and the most effective way to prevent pathogenic transmission is to clean the host environment using disinfectants. In this study, we identified which disinfectants most effectively inhi...
full textPhotolysis of hydrogen peroxide, an effective disinfection system via hydroxyl radical formation.
The relationship between the amount of hydroxyl radicals generated by photolysis of H(2)O(2) and bactericidal activity was examined. H(2)O(2) (1 M) was irradiated with laser light at a wavelength of 405 nm to generate hydroxyl radicals. Electron spin resonance spin trapping analysis showed that the amount of hydroxyl radicals produced increased with the irradiation time. Four species of pathoge...
