“…Microwave discharge of an O 2 /H 2 gas mixture at low pressure followed by low-temperature condensation of the discharge products results in a mixture of H 2 O x (x = 1-4). The mixture composition and the content of hydrogen peroxides were studied by Raman spectroscopy 42 . As the content of O 2 in the gas mixture increases, the content of hydrogen peroxide in the mixture decreases monotonically, whereas the fraction of higher oxides grows.…”

“…As the content of O 2 in the gas mixture increases, the content of hydrogen peroxide in the mixture decreases monotonically, whereas the fraction of higher oxides grows. In particular, the molar fraction of HOOOH in the condensate exceeds 0.3 at 70 vol% O 2 , whereas the content of the other oxides amounts to ∼0.25 (H 2 O and HOOH each) and >0.1 (HOOOOH) 42 . The thermal decomposition of hydrotrioxides of certain silanes and germanes to give HOOOH was studied in Ref.…”

The review discusses the results of studies on the chemistry of organic trioxides ROOOR (R = H or an organic radical) carried out in the past years. The spectral identification, structure, thermal stability and chemical properties of HOOOH, HOOO ⋅ , hydrotrioxides, open‐chain and cyclic trioxides (including fullerene ozonides) are described. The significance of trioxides for biochemistry, environmental chemistry, and organic synthesis is much higher than it was believed previously. The chemical reactions that these compounds undergo resemble those of peroxides. However, the temperature range in which trioxide reactions occur is shifted considerably towards low temperatures. Homolytic decomposition at one of the OO bonds is the most typical reaction of trioxides. Trioxides are liable to induced and catalytic decomposition. Hydrotrioxides demonstrate high oxidative activity. Decomposition of some trioxides is accompanied by efficient generation of singlet oxygen.

“…The infrared spectrum of hydrogen trioxide is reasonably understood, even though some discrepancies exist for the vibrations of the oxygen framework, as one of them has been suggested to belong to H 2 O 4 . A recent landmark investigation by Levanov et al showed that it is possible to obtain H 2 O 4 in quantities large enough to obtain its Raman spectrum. As noted by Levanov et al, this was the first time convincing evidence was provided for the existence of hydrogen tetroxide.…”

Following our investigations on hydrogen polyoxides, herein we employed coupled cluster theory in conjunction with Dunning's correlation consistent basis sets and density functional theory to study HOOOOOH (H2O5). The infrared spectra of H2O5 and its three deuterated isotopologues, as well as those of the five single‐substituted 18O isotopologues are discussed in detail. Internal valence coordinates were employed to classify the vibrational modes. The Raman activity is reported to help in the identification of hydrogen pentoxide. The suggested enthalpy of formation is ΔHf,298° (HOOOOH) = 1.4 ± 1.5 kcal/mol. This value includes corrections for relativistic and core‐valence effects as well as anharmonic corrections to Zero‐point energy corrections. © 2013 Wiley Periodicals, Inc.

“…[1] Some of the most promising methods are:a )ozone reduction, [2] b) decomposition of hydrotrioxides with retention of the trioxide function, [3] c) reaction of hydrogen peroxide with ozone, [4] d) microwave discharge of an O 3 /O 2 / H 2 gas mixtures at low pressure followed by low-temperature condensation, [5] and d) photoelimination from ametal hydroperoxo-hydroxo complex. [6] However,s olutions of HOOOH in various solvents are usually contaminated with anumber of by-products,s uch as oxidation products and HOOH.…”
