Abstract:
A method of purifying dimethyl sulfoxide includes distilling a dimethyl sulfoxide-containing liquid in the presence of sodium carbonate in an inert gas atmosphere to distill out dimethyl sulfoxide, an amount of the sodium carbonate with respect to 100 g of pure dimethyl sulfoxide in a residual liquid after the distillation being 6 times or more the amount of the sodium carbonate with respect to 100 g of the pure dimethyl sulfoxide in the dimethyl sulfoxide-containing liquid before the distillation.

Claim (Index 15):
The method according to  claim 9 , wherein, after water in the dimethyl sulfoxide-containing liquid is distilled out as an early distillate, the dimethyl sulfoxide is distilled out as a main distillate.
