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.

Prospective Approach to the Anaerobic Bioconversion of Benzo- and Dibenzothiophene Sulfones to Sulfide.

Olga Senko et al.

Molecules (Basel, Switzerland), 24(9) (2019-05-08)

Sulfur recovery from organic molecules such as toxic sulfones is an actual problem, and its solution through the use of environmentally friendly and nature-like processes looks attractive for research and application. For the first time, the possible bioconversion of organic
