Dimethyl sulfide has a characteristic odor commonly described as cabbage-like.It becomes highly disagreeable at even quite low concentrations. Some reports claim that DMS has a low olfactory threshold that varies from 0.02 to 0.1 ppm [clarification needed] between different persons, but it has been suggested that the odor attributed to dimethyl sulfide may in fact be due to disulfides ...
The crude dimethyl sulfide product was purified by distillation and could then be used to produce DMSO. When Gaylord closed its Bogalusa plant in 2010, it changed its process technology to manufacture DMS from methanol and hydrogen sulfide gas via gas phase thioetherification. This is the dominant method used worldwide to make DMS and there are ...
The bond dissociation energies for dimethyl sulfide and dimethyl ether are respectively 73 and 77 kcal/mol (305 and 322 kJ/mol). Sulfides are typically prepared by alkylation of thiols. Alkylating agents include not only alkyl halides, but also epoxides, aziridines, and Michael acceptors. [6] They can also be prepared via the Pummerer ...
Thus, the two substrates of this enzyme are trimethylsulfonium and tetrahydrofolate, whereas its two products are dimethyl sulfide and 5-methyltetrahydrofolate. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases.

Bacteria in environments both with and without oxygen can also convert methanethiol to dimethyl sulfide (DMS), although most DMS in surface seawater is produced by a separate pathway. [6] Both DMS and methanethiol can be used by certain microbes as substrates for methanogenesis in some anaerobic soils.
The use of triphenylphosphine, thiourea, zinc dust, or dimethyl sulfide produces aldehydes or ketones. While the use of sodium borohydride produces alcohols. (R group can also be hydrogens) The use of hydrogen peroxide can produce carboxylic acids. Amine N-oxides produce aldehydes directly. [8]
