Dimethyl sulfide – (CH₃)₂S
Dimethyl sulfide is the most common sulfur compound found in nature. It is responsible for the smell of the sea for example and is also produced during the cooking of various vegetables and seafood.
In the food industry, dimethyl sulfide is used as a seasoning component and creates desirable flavors in many foods such as cocoa, tea, and wine.
In the petrochemical industry, dimethyl sulfide is used in the refining of petroleum and in other production processes, such as controlling the formation of coke and carbon monoxide. In addition, dimethyl sulfide is used for dust control in steel rolling mills and in a number of organic syntheses.
Dimethyl sulfoxide is also used as a solvent for paints, as a paint stripper, and as a solvent and oxidizer in organic chemistry and biotechnology.
Dimethyl sulfide is a highly flammable chemical and is classified as hazardous to health. It is very volatile, the vapors are heavier than air and form an explosive mixture with it.
When heated or burned, the gas decomposes to form corrosive, toxic vapors (hydrogen sulfide, nitrogen oxides).
If the gas is inhaled, consciousness may be disturbed or even lose consciousness.
The TA-Luft counts dimethyl sulfide as a total carbon.
Thus, 500 g/h and 50 ppm mass concentration apply as limit values in the volume flow.
We neutralize dimethyl sulfide in the exhaust air in an environmentally friendly manner with catalytic exhaust air purification via UV ozone and a downstream activated carbon filter.
