title: [Ozonolysis of methacrolein and methyl vinyl ketone in aqueous solutions].
abstract: The experimental simulation was employed to study the aqueous-phase ozonolysis reactions of methacrolein (MAC) and methyl vinyl ketone (MVK) in the atmosphere, at the 25.0 degrees C +/- 0.1 degree C temperature and 1.0 x 10(5) Pa pressure of air. In both MAC and MVK ozonolysis reactions in water, formaldehyde, methylglyoxal, hydrogen peroxides (H2O2) and hydroxymethyl hydroperoxides (HMHP) were found; and their yields (%) were determined: 49.9 +/- 2.9, 26.6 +/- 3.9, 4.6 +/- 0.4 and 10.0 +/- 0.8 respectively for MAC; 40.8+/- 2.2, 40.7 +/- 3.5, 6.8 +/- 0.5 and 10.4 +/- 0.8 respectively for MVK. Finally, the reaction mechanisms are deduced to explain the formation of products observed.
