Junyuanpetroleumgroup.com - a key manufacturer of pentanes, hexanes, heptanes and Dfluids in China
A key manufacturer of n-Pentane, Isopentane, Cyclopentane, n-Hexane, Isohexane & n-Heptane in the world solvent market.
In simpler terms, let’s delve into the differences and applications of DTBPS (Di-tert-butyl Polysulfide) and DMDS (Dimethyl Disulfide). These two chemical compounds play distinct roles in various industrial processes. By offering both options, Junyuan Petroleum Group ensures flexibility and meets diverse customer needs. Let’s explore their unique features and why they coexist in the market.
Let me introduce both TDBPS (Di-tert-butyl Polysulfide) and DMDS (Dimethyl Disulfide) to clarify any doubts and provide a reasonable explanation for their coexistence.
Reason for Coexistence: Having both TDBPS and DMDS allows Junyuan Petroleum Group to cater to different customer needs and specific applications. While TDBPS offers environmental safety and high sulfur content, DMDS remains a reliable choice for traditional sulfiding processes. By providing both options, Junyuan Petroleum Group ensures flexibility and suitability for various scenarios.
TDBPS (Di-tert-butyl Polysulfide):
Composition: TDBPS is primarily composed of tetra and penta sulfides.
Sulfur Content: It contains the highest sulfur content among manufactured polysulfides.
Usage: TDBPS finds application in the metalworking lubricant markets. It contributes to improving lubricity, reducing friction, and enhancing machining processe.
Advantages: TDBPS is environmentally safer, non-flammable, and has a friendly odor. It also exhibits low toxicity.
Decomposition Temperature: TDBPS decomposes at a lower temperature of 150°C3.

DMDS (Dimethyl Disulfide):
Composition: DMDS is a catalyst sulfiding agent.
Sulfur Content: DMDS contains 68% sulfur.
Usage: DMDS serves as a sulfiding agent, working in conjunction with a reducing agent like hydrogen. Its purpose is to convert metal oxide species into a crystalline metallic sulfide phase in situ for hydrotreating catalysts. By conducting the reaction within the process unit, operators maintain precise control and optimize catalyst activity while ensuring safety.
Advantages: DMDS is widely used for catalyst sulfiding and has been a traditional choice. However, it has an offensive odor and is flammable2.
Decomposition Temperature: DMDS decomposes at 200°C (in the presence of catalysts).
