  DMDS is used to prepare catalysts for hydrodesulfurization, because of its high sulfur content and low decomposition temperature. Refineries use it instead of other sulfur spiking agents for catalyst sulfiding because it has more sulfur per pound than dimethyl sulfide (DMS) or di- tert -butyl polysulfide (TBPS). Once injected to a hydrotreater or hydrocracker, It decomposes to form H S. The H S reacts with the metal oxides on the catalyst, converting them to the active metal sulfide form.
  
  DMDS also works as an effective product for operators in the petrochemicals industry who must protect their steam-cracking coils against the formation of coke and carbon monoxide.
  
  DMDS is utilized in the preparation of 4-(methylthio)phenol which is used in the production of various pesticides. DMDS and chlorine are reacted with borontrifluoride phenoxide to produce 4-(methylthio)phenol. Thiophene and DMDS are blended with combustible hydrocarbon fuel gas to impart a gassy odor to the fuel gas.
