Mechanism of the Formation of Hydrogen Tetroxide and Peroxide via Low-Temperature Interaction between Hydrogen Atoms and Molecular Oxygen

摘要

A mechanism and kinetic model for the synthesis of peroxide radical condensate via the low-temperature interaction of hydrogen atoms with O_2 molecules is proposed. The main components of the reaction, hydrogen tetroxide H_2O_4 and hydrogen peroxide H_2O_2, are formed in a low-temperature liquid layer formed near the cold surface during synthesis. Molecules of H_2O_4 and H_2O_2 are stabilized by transitioning to the solid phase. The dependences of the NО_2/NН_2О_2 ratio on the ratio of concentrations of H and O_2 in the gas phase, calculated on the basis of the model, are consistent with the experimental data.
