Application
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.
