The enthalpies of the formation and decomposition of hydrogen trioxide are estimated from the heating curves of peroxide-radical condensates synthesized from gaseous O2 + H2 mixtures. Enthalpy of decomposition Н2О3(aq.) → Н2О(liq.) + О2(gas) is −31.2 ± 1.5 kcal/mol, and enthalpy of formation Δf H(H2O3, aq.) =–37.5 ± 1.6 kcal/mol. Both values correspond to the temperature range of 240–265 K.
根据由气态O 2 + H 2混合物合成的过氧化物-自由基缩合物的加热曲线估算三氧化氢的形成和分解焓。分解Н焓2 О 3(水溶液)→Н 2 О(LIQ。)+О 2(气体)是-31.2±1.5千卡/摩尔,和形成Δ的焓˚F ħ(H 2 ö 3,水溶液) = –37.5±1.6 kcal / mol。这两个值都对应于240–265 K的温度范围。

THE formation and decomposition of a higher hydrogen peroxide H2O4 has been described in recent Russian literature. Much of this work dealt with the existence of condensed HO2 radicals or molecular H2O4 at low temperatures ; for example, Kobozev et al., Reznitskii et al., and Gorbanev1 investigated the reaction between atomichydrogen and liquid ozone at −196°C.
