APPLICATIONS
Organosulfur compounds are widely used in refineries, steamcrackers, aromatic extraction and petrochemical manufacturing as they acts as;
  • Hydrotreating catalysts
  • Initial catalyst improvers
  • Sulfur sources
  • Catalyst presulfiding
  • Natural gas sulfur recovery

Organosulfur compounds are also used in;

  • Organic synthesis as organosulfur sources into target organic molecules for the manufacture of pharmaceuticals, adhesives biocides and agricultural products.
  • Polymer production
  • Lubricant and fuel additives for extreme pressure functionality
  • Extraction and reaction solvent
  • Metal treatment
  • Fungicide
3-Sulfolene is a source cisoid butadiene (Diels-Alder reaction) and sulfur dioxide. It is an intermediate in the production of sulfolane. Sulfolene is also used as a catalyst.
