Popis: | A study was performed to find and then to optimize the conditions under which alkaline solutions of H2O2 convert 8-oxyquinoline into an oligomeric oxide. According to infra-red and ultra-violet spectroscopy and gel permeation chromatography data, the oligomer consists mostly of oxyquinolineN-oxide repeat units. A kinetic study of the decomposition of this oligomeric oxide under the action of sulphuric acid in the temperature range 313–343 K showed that up to 6.8 litres of free oxygen were liberated per 100 g of the oligomer. The first-order rate constant at 333 K and activation energy for decomposition were6.05 × 10−4s−1 and 99.2 kJ mol−1 respectively. |
