FIELD: chemistry.
SUBSTANCE: invention relates to production of dimethyl sulphoxide (DMSO) which is widely used in organic synthesis. According to the invention, dimethyl sulphide is oxidised with chlorine dioxide with molar ratio of sulphide to chlorine dioxide equal to 1:0.5 at temperature 7-10°C. The invention also describes preferable conditions for conducting the process.
EFFECT: improved method.
