Oxygen Reaction

The catalysis of the combustion of hydrogen and oxygen by nitrogen peroxide was first discovered by Dixon, and later studied quantitatively by Gibson and Hinshelwood, Thompson and Hinshelwood, and by Norrish and Griffiths. Thompson and Hinshelwood found that the ignition temperature of hydrogen was depressed by over 100° C by the addition of less than 0·1% (0·1 mm) of nitrogen peroxide, but that this sensitized ignition was confined within a narrow range of pressures of nitrogen peroxide, the upper limit increasing with rise of temperature and decreasing with increasing pressure, whilst the lower limit was only slightly affected. Norrish and Griffiths found that, within similar limits of pressure of nitrogen peroxide, rapid reaction but no explosion occurred when an axial tube was used for the inlet of gas. This reaction was accelerated by irradiation with light which decomposes nitrogen peroxide to nitric oxide atomic oxygen, but not by light which is absorbed without producing photochemical decomposition. Without the axial tube, explosions occurred, but the ignition temperature was not affected by irradiation.

Epitaxy of cupric oxides, such as the high temperature superconductor YBa2Cu3O7, using “vacuum” techniques requires either activated forms of oxygen, such as atomic oxygen, oxygen plasma, or ozone, or a relatively high pressure of molecular oxygen. In contrast, cuprous oxides (those with formal valence of copper less than +2) can be grown epitaxially in molecular oxygen at pressures below 10−4 Torr. We have explored this regime of epitaxial growth because of the possibility of forming DyBa2Cu3O7 through low temperature ex situ oxidation of DyBa2Cu3O6. We find that the dominant phases growing epitaxially on MgO are CuDyO2, Cu2O, CuBa2O2, DyBa2Cu3O6, and the barium-rich perovskite solid solutions. Sticking coefficients of barium and dysprosium depend on substrate temperature and flux composition for substrate temperatures between 550° and 700 °C. We have obtained superconducting films by annealing Dy-rich, Cu-deficient films in oxygen at 400 °C. The nonstoichiometry (with respect to DyBa2Cu3O6) appears to stabilize “DyBa2Cu3O6,” at low oxygen pressures. We also discuss the use of copper in effusion cells.

The effect of the presence of nitrogen, oxygen, and nitric oxide on the reaction between cis-2-pentene and oxygen atoms has been investigated at room temperature (25 ± 2 °C). For production of oxygen atoms use was made of mercury-photosensitized decomposition of nitrous oxide and of the photolysis of nitrogen dioxide at 3660 Å.In the N2O work, the presence of molecular oxygen induced the formation of acetaldehyde, propanal, methanol, and ethanol. In the NO2 work, the amounts of acetaldehyde, propanal, and ethyl nitrate formed increased rapidly with increasing pressure of molecular oxygen. Possible reaction mechanisms for the formation of these compounds are discussed.Additional information was obtained on the pressure-independent fragmentation in the reaction of oxygen atoms with cis-2-pentene.
