Paper Abstract

We have investigated the advantages of using laser-initiation for the synthesis of cumenehydroperoxide and t-butylhydroperoxide. Laser-initiation significantly improves the oxidation rates of cumene in the liquid phase and iso-butane in the vapor phase (using HBr promoters) with moderate photoefficiencies (418 and 490 respectively). The primary effect of laser-initiation is to reduce the induction period of the reaction. For the oxidation of cumene the beneficial effect of laser initiation is strongly dependent on laser wavelength, alternately enhancing (at 351 nm) or inhibiting (at 249 nm) the oxidation rate. For isobutane oxidation, laser-initiation also minimizes the HBr depletion rate relative to oxidation rate.
