ABSTRACT:
Dimethylsulfoxide is prepared by a method which comprises adding separately dimethylsulfide and an aqueous solution of about 30 to 60 percent by weight hydrogen peroxide to a stirred aqueous liquid reaction medium under an atmosphere of inert gas, said reaction medium containing sufficient dimethylsulfoxide to solubilize the dimethylsulfide.
Dimethylsulfoxide has many known uses, particularly as a solvent in spinning polymers, extracting hydrocarbons and the like.
