β-Ionone was pyrolyzed under helium atmospheres at 300
400
500
600
700 and 800 ℃ respectively
and the pyrolysates were analyzed by online gas chromatography /mass spectrometry (GC/MS). The results showed that (1) Forty-eight substances were detected from the pyrolysates at 800 ℃; (2) At 600 ℃ only 10.765% of β-ionone was pyrolyzed. The pyrolysis reaction became more intensive at 700 and 800 ℃
18.149% and 21.286% of β-ionone was pyrolyzed; (3) the percentage of aromatic compounds increased with the increase of pyrolysis temperature. The possible pyrolysis mechanism of β-ionone was preliminarily investigated based on the major pyrolysates.
