A method for identifying the sulfur compounds in industrial mixed alkanes was developed.Mercaptan was first extracted from the sample with a KOH solution,and then the residue was treated with a AgNO₃ solution,which precipitated with thioether and was separated from thiophene.The mercaptan,thioether and thiophene were separated and enriched from industrial mixed alkanes before analysis by GC-MS.30 thioether compounds and 5 mercaptan compounds in industrial mixed alkanes were detected.
