Description:
The electron impact (El) mass spectra of 2,6-di-tert-butyl-4-methylphenol (BHT) and certain of its alteration products are described in detail. ccurate mass measurements confirm the element compositions of important fragment ions in the El spectra. Collisionally activated mass spectra are also used to study fragmentation and suggest common ion structures. he reference spectra provide the basis for identifying various alteration products of BHT by capillary gas chromatography/mass spectrometry(GC/MS) without the necessity of isolating individual components. pplication of GC/MS is made to three studies: (i) pyrolysis of hydroperoxy-BHT as a potential pathway to alteration products in food; (ii) GC/MS pyrolysis of hydroperoxy-BHT as a model study; and (iii) alteration of BHT in ethanol/water as food-simulating solvent.
