| Abstract: | Sulfide in diesel oil is separated by oxidation-reduction method. Oxidation conditions of oxidants TBAPI and MCPBA and the separation condition on silica-gel column have been studied in detail. Oxides of TBAPI and MCPBA have been reduced with LiAlH 4 as reductant. Basic structure and type of sulfide separated from diesel oil have been identified by FI-IK and mass spectroscopy. The result shows that the thio-ether compounds in diesel oil are mainly pentacyclide thio-ether, and the thiophene compounds are mostly alkyl thiophene, benzothiophene, dibenzothiophene and its homologies. |
| Keywords: | diesel fuel oxidation desulfurization thiophene |
