Abstract
The thermal behavior and the cleavage mechanism of the electron impact for 5-phenoxymethyl-3-phenylcarbamoyl-2-oxazolidinones derivatives were investigated by the thermal analysis and mass spectrometry. The values of the activation energy were between 90 and 150 kJ mol −1. The rate of thermal decomposition under a nitrogen atmosphere was rapid compared to the rate under an air atmosphere. The distinctions between the products of pyrolysis and EI-mass fragmentation patterns were investigated from the thermogravimetry-trap-gas chromatography/mass spectrometry measurement.
