摘　　要：建立了工业混合烷中含硫有机化合物首先用KOH溶液提取硫醇,再用AgNO3溶液沉淀硫醚,而噻吩类化合物保留在混合烷中的预处理方法。将分离得到含有硫醇、硫醚和噻吩类化合物的3组样品再用GC-MS分别分析各组份,鉴定出工业混合烷中30种硫醚和5种硫醇化合物。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.
