摘要
介绍了用毛细管色谱法测定不同柴油正构烷烃碳数分布的方法,该方法使用GC-MS色、质联用技术和加入已知标准物质增加峰高法及保留指数等色谱规律进行定性,得到了满意的分析结果,同时与德国Clariant公司对同一成品油JCH做正构烷烃的碳数分布的对比分析试验,结果非常吻合。该方法简便、快速、准确、进样量少、灵敏度高,相对偏差小于3.5％。本分析方法可用于油品调合及生产常规分析。
This paper inhoduced a method for the determination of the distribution of carbon numbers in nomcal paraffin hydrocarbons of different kinds of diesel oil. By cappillary chromato gvaphic process. In this peocess the qualitative analysis are earned out by GC - MS integrated chromagraph and mass spectya technic, adopting the method of peak height by adding the known standard substance and reservation index etc,some chromagraphtic rules,for the qualitatiue andlyses. And achi-cued sahsfuctory analying result.To make a contrast with the experiment result for the determinabon of the distribution of carbon numbers in normal paraffin hydrocarbons of the same oil sample JCH,that carried out by clariant Company. Germany. The two results are showned to be identical.The refore,this method is simple, rapid accurate,fener sample offered of high sensitirity relative deviation is lessthan 3.5% . This analysis method can be used the blending of dicsel oil and routine analyses in production.
