Dimethyl Disulfide- DMDS 99.6%

(DMDS Producing Line)


Chemical Formula : C2H6S2

molecular W.T.. : 94.20

Applications :
Used as an activator in hydrodesulphurization process of oil refinery, and in presulfurization process, an inhibitor in cracking coking of petrochemicals, also an intermediate for solvent and pesticides.

DMDS is used in a wide variety of applications, including:

Oil refining: optimal maintenance of production units. DMDS is used in oil refineries as a sulfiding / presulfiding agent to activate the catalysts of hydrotreating units. This is an indispensable but delicate operation. That is why OINO offers its clients .an on-site sulfiding service carried out by highly qualified technicians. OINO has also developed an improved, lower odor version of DMDS .
Petrochemicals: to reduce the number of decoking operations. Operators in the petrochemicals industry must protect their steam cracking coils against the formation of coke and carbon monoxide. DMDS by OINO is the ideal sulfurous product for them. DMDS can be added continuously to the raw materials to maintain an optimal sulfur level, making it possible to reduce the number of decoking operations. The secondary reactions to these operations are easier to control and the production cycles are lengthened.
DMDS is also used in various other sectors, including:

Fine chemicals, as chemical intermediate
Metallurgy for its anti-corrosion properties.
