METHOD OF PRODUCING DIMETHYL SULPHONE Russian patent published in 2009 - IPC C07C315/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the processing sulphur-containing organic compounds, specifically to dimethyl sulphone, which can be used in making dyes, medicinal agents, polyacrylene sulphones, as polyacrylonitrile solvent etc. A method is described for electrochemical synthesis of dimethyl sulphone, involving electrolysis of 1.0-3.0 M dimethyl sulphone in aqueous NaOH solution in a diaphragmless cell with anode current density of 0.01-0.02 A/cm².

EFFECT: easier processing dimethyl sulphone, exclusion of a large number of operations and use of expensive reagents, toxic solvents, as well as strong oxidising agents such as ozone, nitric acid, hydrogen peroxide, as well as possibility of obtaining highly pure dimethyl sulphone and continuous electrosynthesis with automatic control of the entire process.
