Dibenzothiophene oxide

Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It is a colourless solid that is chemically somewhat similar to anthracene. This tricyclic heterocycle, and especially its alkyl substituted derivatives, occur widely in heavier fractions of petroleum.
