Description

General description

Dimethyl sulfide is the major biogenic, volatile sulfur compound that is released from the ocean to the atmosphere. It plays a main role in the global sulfur cycle.

Application

Dimethyl sulfide undergoes thiolation reaction with hydrogen sulfide (H₂S) in the presence of tungsten-zirconia (WO₃/ZrO₂) catalyst to form methanethiol.
