Abstract

Procedure for the preparation of dimethyl sulfoxide by anodic oxidation of dimethyl sulphide in the presence of water, of one or more electrolytes such as dimethyl sulfoxide as an organic solvent, characterized in that sulphide is continuously added to the electrolysis tank of dimethyl, water and one or more electrolytes, the electrolysis is carried out maintaining a practically constant concentration of dimethyl sulphide, dimethyl sulfoxide, water and the electrolyte or electrolytes in the cell and at the same time it is removed and treated I continue an aliquot of the electrolysis mixture.
