Abstract The dark-phase reaction of olefin-ozone-sulfur dioxide was studied in an attempt to elucidate the mechanism involved in the oxidative consumption of the sulfur dioxide. The effect of several variables on the reaction stoichiometry and on the aerosol production are reported. The variables include the reactant concentrations, the relative humidity, molecular oxygen concentration, and the olefin species although propylene was the primary olefin studied. The stoichiometry was found to be a smooth function of the olefin/ozone initial concentration and was essentially unaffected by varying the relativity humidity over the range studied or by the addition of sulfur dioxide. The molecular oxygen concentration had a significant effect on the reaction stoichiometry and on the product formation in the propylene-ozone thermal reaction. A tentative mechanism is advanced for the oxidative consumption of the sulfur dioxide and the aerosol formation, growth and decay is explained in terms of the processes of nucleation condensation and coagulation.
