| Dibenzothiophene Usage And Synthesis |
| Description | Dibenzothiophene (DBT) is an organosulfur compound found in crude oil and petroleum. It is a colourless solid that is chemically somewhat similar to anthracene. Dibenzothiophene is used as a chemical intermediate in cosmetics and pharmaceuticals (NLM, 2006).It is used to investigate the effect of sulfur compounds in gasoline range during the fluid catalytic cracking (FCC) process. |
| Chemical Properties | Dibenzothiophene is a yellow-green, crystalline solid with an mp of 99.5°C and a bp of 332.5°C. It is soluble in ethanol, benzene, chloroform, and methanol but insoluble in water. Its dipole moment is 0.83 D. It is quite stable under normal temperature and pressure. |
| History | Dibenzothiophene was first synthesized in 1870 by Stemhouse by heating biphenyl with iron scrap, but the assigned incorrect structure was corrected by Graebe. The natural dibenzothiophene was isolated from coal tar by Kruber. Besides this, various alkylated dibenzothiophenes have also been isolated from the crude oil, but it was difficult to desulfurize them catalytically. The presence of sulfur in the fuel produces sulfur dioxide when burnt and causes air pollution. Dibenzothiophene is a thermally stable compound and resistant to mild oxidizing agents. Depending on the nature of the oxidizing agent it is oxidized to corresponding sulfoxide and sulfone. There are numerous protocols for the construction of dibenzothiophene but some of them are limited to the synthesis of specific compounds due to noncompatibility of functional groups. |
| Uses | Dibenzothiophene (DBT) can be used as: A starting material for the synthesis of corresponding sulfoxide and sulfone by oxidative desulfurization using various catalysts. A template for the synthesis of surface molecular imprinted polymer (SMIP). SMIP is applicable for the removal of dibenzothiophene during desulfurization of the gasoline. A precursor for the synthesis of DBT based π-conjugating polymers. |
| Uses | Dibenzothiophene is used to investigate the effect of sulfur compounds in gasoline range during the fluid catalytic cracking (FCC) process. |
| Definition | ChEBI: Dibenzothiophene is a mancude organic heterotricyclic parent that consists of a thiophene ring flanked by two benzene rings ortho-fused across the 2,3- and 4,5-positions. It has a role as a keratolytic drug. It is a member of dibenzothiophenes and a mancude organic heterotricyclic parent. |
| Application | Dibenzothiophene is an important representative of polycyclic aromatic hydrocarbons (PAHs). Kinetics of hydrodesulfurization of dibenzothiophene on presulflded molybdenaalumina catalyst has been studied in a high-pressure-flow microreactor. Biodesulfurization of dibenzothiophene by selective cleavage of carbon sulphur bonds by a thermophilic bacterium Bacillus subtilis WU-S2B has been reported. Dibenzothiophene was employed as heavy model sulfur compound to investigate the effect of heavy sulfur compounds on the percentage of sulfur in gasoline range during the Fluid Catalytic Cracking (FCC) process. |
