- DIMETHYL DISULFIDE is
a colorless oily liquid with a garlic-like odor. Denser than water
and slightly soluble in water. Vapors heavier than air. May irritate
skin and eyes. Used to make other chemicals.
- Dimethyl disulfide (DMDS)
is a soil fumigant . DMDS can occur naturally in soil, wetlands,
oceans and outdoor air, and plays a role in the global sulfur cycle.
DMDS is also naturally produced by some plants,including certain
food crops, and can be present in certain dairy products. In the
United States and Europe, DMDS is an approved food additive used for
flavoring.
- Prior to planting,
DMDS can be either injected beneath the soil surface with
specialized
application equipment or applied to the soil surface through a drip
irrigation line
- The EPA concluded that
DMDS fumigant is not likely to get into food crops. Because DMDS can
damage crops, Paladin® is applied prior to planting.
- DMDS has a sulfurous
odor similar to that of garlic and decaying fish. Because of the
distinctive
odor of sulfur compounds, similar to DMDS, they are often added to
natural gas and propane to
warn of leaks and protect people.
- Methyl disulfide is
used as a solvent and pesticide intermediates, fuel and lubricating
oil additives and Coking inhibitor for ethylene cracking furnace and
oil refining equipment etc.
- DMDS (dimethyl
disulfide) is the most common compound used for hydrocracking
catalysts sulfiding in refineries.
- DMDS is used in the
preparation of 4-(methylthio)phenol which is used in the production
of various pesticides.
- Dimethyl disulfide can
be prepared by the reaction between imethyl sulfate and sodium
sulfide. under stirring, sulfur powder was added into sodium sulfide
solution. The above reaction system was heated Up to 80-90℃, after
reaction for 1 h, cooled to about 30 ℃. Dimethyl sulfate was dropped
into the reaction system and the reaction was continued for 2h.
Then, distillation, stratification, Separating waste alkali liquor,
then through distillation and final products are prepared.
- In industry,dimethyl
sulfate method is adopted to synthesize dimethyl disulfide.Solid
sodium sulfide and water are dropped into the reaction kettle ,
heated , temperature is controlled in the range of the of 50 ～60 ℃,
dissolving sodium sulfide, adding equimolar sulfur, remaining the
temperature for 1h, cooling to 45℃， dripping dimethyl sulfate into
the reaction kettle, remaining the temperature for 1h, then through
distillation dimethyl sulfate can be prepared.
- Petrochemicals and
agriculture being the major areas of application, the global DMDS
market has immense potential opportunity to expand very well
