| 摘 要： | 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。 |

| Abstract: | 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% 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. |
