| 摘 要： | 采用程序升温和程序升柱头压的技术建立了一种快速分析汽油中BTEX的气相色谱方法,对汽油中芳烃的分离条件进行了选择,比较了用不同内标的定量分析结果,并测定了几种汽油中的BTEX。该方法可用于直馏汽油、催化裂化汽油、重整汽油、裂解汽油中BTEX和其它芳烃的测定,适合于汽油质量的快速监测分析。

| Abstract: | A quick method for effectively analyzing BTEX in gasoline by gas chromatograph was introduced.Programmed temperature and programmed inlet pressure techniques were used.Optimum conditions for separa ting aromatics in gasoli ne were selected.Measurements with different ISDs were compared.The method can be used to determine BTEX and other aromatics in straight run gasoline,catalytic cracking gasoline,reformated gasoline and pyrolysis gasoline,and especially to monitor the quality of gasoline quickly. |
