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.
