Mainly used as catalyst pre-sulfiding agent in oil refineries, anti-coking additive for ethylene cracking furnaces, soil fumigant for nematode control and fine chemical intermediate. Full dangerous goods export documents, ISO certified, ISO tank & iron drum packaging available.
Dimethyl Disulfide, abbreviated DMDS, also named Methyl Disulfide, CAS 624-92-0, is a high-sulfur organic disulfide liquid widely applied in petrochemical, agriculture and fine chemical manufacturing. Our factory adopts advanced catalytic synthesis & rectification purification process to produce 99.5% high-purity industrial DMDS, removing low-boiling impurities and sulfur-containing by-products to guarantee stable sulfur release efficiency during high-temperature decomposition.
With the highest sulfur mass fraction among common organic sulfides (nearly 68%), DMDS decomposes evenly under heating to generate hydrogen sulfide, which serves as the core sulfur source for catalyst activation. Compared with dimethyl sulfide and carbon disulfide, DMDS features mild decomposition temperature, low carbon deposition and high sulfiding efficiency, and is recognized as the standard sulfiding raw material for global refinery hydrotreating units. It also acts as eco-friendly soil fumigant and key intermediate for pesticide, spice and lubricant additives, supporting bulk industrial continuous supply.
*Catalyst pre-sulfiding agent for hydrodesulfurization, hydrocracking and hydrogenation units; converts metal oxide catalysts into active metal sulfide phase.
*Anti-coking additive for ethylene cracking furnace, PDH/BDH propane dehydrogenation equipment, inhibits carbon deposition on pipeline inner walls.
*Odorant additive for natural gas and fuel gas to assist pipeline leak detection.
Broad-spectrum soil fumigant applied before crop planting for fruits, vegetables and cash crops; suppresses root-knot nematode, fusarium, soil-borne germs and weed seeds, improves crop survival rate and yield.
*Raw material for sulfur-containing pesticides, fungicides and insecticide intermediates.
*Synthetic spice raw material for garlic, onion and savory food flavor formulas.
*Extreme pressure anti-wear additive base stock for industrial lubricants and metalworking fluids.
Organic synthesis sulfur introduction reagent for lab research; solvent for sulfur compound preparation.
It is the primary pre-sulfiding agent for hydrogenation catalysts, decomposes to release H₂S under heating to activate catalyst active components and ensure hydrogenation efficiency.
