Abstract
Photo-oxygenation of 2,3-dimethyl-2-butene was performed using dye-supported solid particles as photosensitizer. Quantitative effects of solid sensitizer concentration and of dye quantity supported on solid particles were investigated. The light absorption rate in the heterogeneous system was assessed by a Monte Carlo simulation. The reaction rate was proportional to the n-th order of light absorption rate, where n was a little less than unity, and to the 0-th order of butene concentration in a feed range of 5 × 101–2 × 102 mol/m3. The rate constant was a function of dye quantity supported on solid particles. This is due to the adsorbate–adsorbate interaction.
