| 摘 要： | 用毛细管流动色谱法分析丙烯在HZSM-5上聚合反应尾气,将此法与气相色谱-质谱联用技术相结合,对各反应产物分别定性,此法即可一次完成丙烯聚合反应产物的完全分离和定量。随着反应温度升高,尾气中芳构化产物增加,C_(4-6)链烃含量下降;丙烯通过齐聚物环化脱氢进行芳构化。

| Abstract: | The capillary flow-gas-chromatography was used in analysing the tail gas of oligomeriza-tion of propene over HZSM-5 zeolite. By combining this method with GC-MS technique, eachproduct was qualified. Using this method, the complicated products of oligomerization of propenewas completely separated and quantified. The content of aromatic hydrocarbons in the tail gaswas increased with the increasement of reaction temperature, while the content of C~(4-6) chainhydrocarbons was decreased. The arcmatization of propene resulted from the cyclization-dehy-drogenation of oligomers of propene. |
