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.
