A Method of Determining the Distrbution of Carbon Numbers in Diesel Oil

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.
