采用在线热裂解-气相色谱/质谱（Py-GC/MS ）联用技术研究了在氦气氛围中β-紫罗兰酮在300、400、500、600、700、800℃下的热裂解行为，结果表明：①β-紫罗兰酮可以裂解生成48种物质；②在600℃以下只有10.765％的β-紫罗兰酮发生裂解；在700、800℃裂解加剧，有18.149％和21.286％的β-紫罗兰酮发生裂解；③同时随着裂解温度的升高，形成的危害性芳香烃类化合物的相对含量也逐渐增大。此外，根据主要裂解产物对β-紫罗兰酮的裂解机理进行了初步探讨。

β-Ionone was pyrolyzed under helium atmospheres at 300,400,500,600,700 and 800 ℃respectively,and the pyrolysates were analyzed by on-line 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% ofβ-ionone was pyrolyzed.The pyrolysis reaction became more intensive at 700 and 800 ℃,18.149%and 21.286%ofβ-ionone was pyrolyzed;(3)the percentage of aromatic compounds increased with the increase of pyrolysis temperature.The possible pyrolysis mechanism ofβ-i-onone was preliminarily investigated based on the major pyrolysates.
