特丁基对苯二酚的电子轰击质谱研究
Electron Ionization Mass Spectrum Research on Tert-Butyihydroquinone
摘要
Abstract
Tert-butylhydroquinone(TBHQ) as a food additive was researched by electron impact mass spectrometry (EI-MS). Based on the analysis of fragments appeared in the mass spectrum, as well as the structure characterizations of these compounds, some frag-mentation rules were obtained. Results show that the EI-MS of TBHQ produces three com-pound-specific fragment ions; the m/z 166 molecular ion, the m/z 151 fragment ion which resulted from a methyl group loss of the molecular ion, and the m/z 123 fragment ion which resulted from a methyl group and the CO loss from m/z 166. At the same time, based on the related mass spectrum, the fragmentation mechanism of TBHQ was discussed.关键词
