Summary
An HPLC fluorescence method for quantitative and qualitative hydroperoxide analysis was improved, so as to determine linear hydroperoxides and hydroxy hydroperoxides up to a chainlength of seven carbon atoms.
The hydroperoxide products of ozonolysis of a number of alkenes were determined under three sets of ozonolysis conditions: 1. concentrations of 4 ppm in dry synthetic air, 2. concentrations of 140 ppm in synthetic air at 100 % relative humidity and 3. concentrations of 100 ppm in water.
The main products of ozonolysis in dry air were alkyl hydroperoxides, while in aqueous solution 1-hydroxyalkyl hydroperoxides were the only products observed. In humid air at the higher concentrations, both types of products were present, and similar results were obtained when ozone was bubbled through aqueous solutions of the alkenes.
A mechanism consistent with these results is postulated.
