Dimethyl sulfite Chemical Properties,Uses,Production
Chemical Properties
CLEAR COLORLESS TO PALE YELLOW LIQUID
Uses
The conformations and vibrational spectra of dimethyl sulfite was studied by matrix-isolation fourier transform infrared spectroscopy and to study its conformational selective aggregation. It may be used in organic synthesis.
Preparation
Dimethyl sulfite is prepared from a 1:2 ratio of thionyl chloride and methanol. The reaction can be catalyzed by tertiary amine bases and likely proceeds via the chlorosulfinate (MeOS(O)Cl), this intermediate will exist only fleetingly in the presence of methanol and as such its decomposition to methyl chloride and sulfur dioxide (via the slower SNi mechanism) is not observed to any great extent.
SOCl2 + 2 CH3OH → (CH3O)2SO + 2 HCl
Application
The conformations and vibrational spectra of dimethyl sulfite was studied by matrix-isolation fourier transform infrared spectroscopy and to study its conformational selective aggregation.
Dimethyl sulfite may be used in organic synthesis. It is used as an additive in some polymers to prevent oxidation. It is also a potentially useful high energy battery electrolyte solvent.
Definition
ChEBI: Dimethyl sulfite is a sulfite ester.
General Description
Dimethyl sulfite is an insect repellent and also experimentally identified as a mutagenic agent.
