Description and Uses
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.
Dibenzothiophene is used to investigate the effect of sulfur compounds in the gasoline range during the fluid catalytic cracking (FCC) process. It can also 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.
