摘要
采用热裂解-气相色谱/质谱(PY-GC/MS)联用技术研究了乙酸芳樟酯在350℃及900℃下的热裂解行为。结果表明:(1)不同的裂解温度直接影响生成产物的类型和相对含量;(2)乙酸芳樟酯可裂解生成41种物质,在350℃及900℃下,约有29.6%和41.3%的乙酸芳樟酯发生了热裂解;(3)随着裂解温度的升高,形成的危害性芳香烃类化合物(甲苯、对甲苯等)的相对含量有增加。根据乙酸芳樟酯裂解产物的种类和相对含量的变化,对其裂解产物的形成机理进行了探讨。
The pyrolysis of linalyl acetate at 350℃ and 900℃ was investigated by Pyrolysis Gas Chromatography/Mass Spectrometry(PY-GC/MS).The results indicated that(1)the pyrolysis temperature directly affected the pyrolysis pattern and the relative content of the products;(2)a total of 41 products were identified.29.6% and 41.3% of linalyl acetate was pyrolyzed at 350℃ and 900℃;(3)the percentage of aromatic compounds increased with the increase of pyrolysis temperature increased.According to the relative content and the category of the pyrolysis products,the pyrolysis mechanism of linalyl acetate was preliminarily investigated.
