Abstract
  • 2, 4-Decadienal was autoxidized by subjecting a purified sample to an atmosphere of pure oxygen for 14 hours. A qualitative analysis of the autoxidative degradation products was made utilizing tandem gas chromatography and mass spectrometry. Additional information was obtained from the determination of the melting point of the DNP-hydrazone derivative and infrared absorbancy data. Positive identification was claimed when the mass spectrum of the unknown compound was matched with an authentic fragmentation pattern. Concurrent relative retention time was confirmatory. Pentane, diethyl ether, furan, ethanal, hexanal, acrolein, 2-octenal, benzaldehyde, glyoxal, fumaraldehyde, hexanoic acid, 2-octenoic acid, and 2, 4-decadienoic acid were all positively identified. Six compounds tentatively identified are benzene, ethanol, butenal, 2-heptenal, acetic acid and naphthodioxane. The first known mass spectrum of but-2-en-1, 4-dial is included.
