Synthesis of peroxy-radical condensates from mixtures H2+O2

Abstract

One of the methods of synthesis of peroxy-radical condensates is the condensation at liquid nitrogen temperature of H2+O2 mixture, dissociated in an electrical discharge at low pressure. Peroxy-radical condensates are considered to contain substantial quantities of higher hydrogen peroxides H2O3 and H2O4. The present work investigates the influence of experimental parameters on synthesis of peroxy-radical condensates from H2+O2 mixture, analyses the relevant literature, and recommends the optimal experimental conditions for the synthesis. The synthesis is carried out in the U-tube electrical discharge reactor (inner diameter ~15 mm), immersed into liquid nitrogen, at sufficiently low pressure (0,5–1 Torr). The maximum conversion of initial O2 into higher hydrogen peroxides was observed at the composition of initial gas mixture 66,7% H2+33,3% O2.
