Abstract
The reaction was run in a one-dimensional reactor with equal partial pressures of 2 Torr of ozone and 2-butene at $20^{\circ} C$. At the end of the reactor, the reaction mixture was pumped through the microwave absorption cell at pressures around 50 mTorr. Reaction products were analyzed by measuring several known microwave transitions of a compound. The signal-to noise ratio of weak transitions was enhanced by summation of up to 100 sweeps. Eleven species were unambiguously identified with this procedure. Among them were secondary ozonide, epoxides, aldehydes and carboxylic acids. Several other species were searched for but could not be detected. The identified reaction products parallel those of a similar investigation of the ozonolysis of ethylene. Implications on the reaction mechanism will be discussed.
