Cylinder of methanethiol gas. Methanethiol is mainly used to produce the essential amino acid methionine, which is used as a dietary component in poultry and animal feed. [10] Methanethiol is also used in the plastic industry as a moderator for free-radical polymerizations [10] and as a precursor in the manufacture of pesticides.
It is used is for the production of borane dimethyl sulfide from diborane: [19] B 2 H 6 + 2 (CH 3) 2 S → 2 BH 3 ·S(CH 3) 2. Oxidation of dimethyl sulfide gives the solvent dimethyl sulfoxide. Further oxidation affords dimethyl sulfone. As illustrated above by the formation of its adduct with borane, dimethyl sulfide is a Lewis base.
DMSP is broken down by marine microbes to form two major volatile sulfur products, each with distinct effects on the environment. One of its breakdown products is methanethiol (CH 3 SH), which is assimilated by bacteria into protein sulfur. Another volatile breakdown product is dimethyl sulfide (CH 3 SCH 3; DMS).
The complex cis-VOCl 2 (SMeEt) 2 exists as meso- and a pair of enantiomers. [7] In complexes of thioethers of the type S(CH 2 R) 2 (R ≠ H), the methylene protons are diastereotopic . Examination of the NMR spectra of such complexes reveal that they undergo inversion at sulfur, without dissociation of the M-S bond.
In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol. This method is employed for the industrial synthesis of methanethiol: CH 3 OH + H 2 S → CH 3 SH + H 2 O. Such reactions are conducted in the presence of acidic catalysts. The other principal route to thiols involves the addition of hydrogen sulfide to ...
The molecular formula C 2 H 6 S (molar mass: 62.13 g/mol, exact mass: 62.0190 u) may refer to: Dimethyl sulfide (DMS), or methylthiomethane Ethanethiol , or ethyl mercaptan
