Oxidation of organic compounds by ozone on a surface: 1. Ozonization of adamantane on silica gel

Article abstract of DOI:10.1007/BF01433972

Adamantanol was obtained by the ozonization of adamantane, at -78°C, adsorbed on silica gel. Ozone does not decompose on silica gel in the absence of a substrate. Ozonization of adamantane on silica gel is accompanied by chemiluminescence in the IR region. The chemiluminescence quenching is of first-order with the effective rate constant k′. In the range from 0.4 to 5 mmol, k′ depends linearly on the amount of adamantane adsorbed on the silica gel. The activation energy E_a = 9.97±1.89 kcal mol^-1 and the pre-exponential factor A = (2.76±0.52)·10⁶ were calculated from the temperature dependence of k′.
