Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
It is based on a direct reaction between methane and oleum at around 50 °C and 100 bar in the presence of a potassium persulfate initiator. [10] Further addition of sulfur trioxide gives methanedisulfonic acid instead. [11] This technology was acquired and commercialized by BASF in 2019. [12]
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...
Organosulfur chemistry is the study of the properties and synthesis of organosulfur compounds, which are organic compounds that contain sulfur. [1] They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.g., saccharin.

Sulfur polycations, S 8 2+, S 4 2+ and S 16 2+ are produced when sulfur is reacted with oxidising agents in a strongly acidic solution. [1] The colored solutions produced by dissolving sulfur in oleum were first reported as early as 1804 by C.F. Bucholz, but the cause of the color and the structure of the polycations involved was only ...
However, all these early synthetic routes suffered from numerous byproducts. A higher-yielding synthesis was introduced by Hilmar Johannes Backer in 1929, treating dichloromethane (CH 2 Cl 2) with potassium sulfite under hydrothermal conditions to get a methionate salt.
