Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used the HH Sulfide sulfur specific capillary column separation method to separate sulfides in straight run diesel. GC/MS was used for qualitative analysis, and more than 50 cyclic sulfide sulfides and more than 10 dibenzothiophene sulfides were retrieved from the separated products. The sulfur-containing compounds (mainly dibenzothiophenes) in straight run diesel were oxidized by H2O2-HCOOH, and the oxidation products of sulfides were extracted with benzene. The GC/MS qualitative results showed that dibenzothiophene sulfides were correspondingly converted into their sulfones. Quantitative analysis of sulfides before and after oxidation was conducted using GC/FPD.
