| 中文摘要:采用在线热裂解/气相色谱-质谱联用技术(Py/GC-MS)对壬酸香草酰胺(PAVA)的热裂解行为进行了研究，在氦气氛围中考察了不同裂解温度和裂解时间对PAVA裂解的影响，通过GC-MS对裂解产物进行定性和半定量分析。结果表明，随着裂解温度的升高，PAVA裂解率快速提高，裂解产物也进一步增多，当裂解温度达到700 ℃以上时，可裂解出壬酰胺、2 甲氧基 4 甲基苯酚、1 己烯、壬基腈、壬醛等14种产物。同一温度下随着裂解时间的延长，PAVA的裂解率逐步升高，裂解产物发生了进一步的裂解。根据热裂解产物及主要裂解产物的含量变化，初步推断了PAVA的裂解规律。 |

| Abstract:The pyrolysis behavior of pelargonic acid vanllylamide(PAVA) was investigated by gas chromatography-mass spectmmetry with on line pyrolysis(Py/GC-MS) in the presence of helium.The influence factors of PAVA pyrolysis behavior such as different temperatures and different time were studied.GC-MS was used for the qualitative and semi quantitative analyses on PAVA pyrolysis products.The results indicated that pyrolysis temperature had a significant effect on the types and relative contents of pyrolysis products.14 products were detected when the temperature reached 700 ℃ above,including nonanamide,2 methoxy 4 methylphenol,1 hexene,nonanenitrile,nonaldehyde,etc.The pyrolysis rate of PAVA increased gradually with time increasing.According to the pyrolysis products and their contents,the pyrolysis regulation for PAVA was preliminarily dicussed. |
