Applications:
DMSO is a solvent for many gases, synthetic fibers, paint, hydrocarbons, salts, and natural products. Because it is aprotic, relatively inert, nontoxic, and stable at high temperatures, it is a frequently used solvent for chemical reactions.
The multi-step carbon fiber manufacturing process relies on the use of DMSO as a processing solvent. DMSO is of great value in spinning polyacrylonitrile (PAN) fibers, a precursor to carbon fiber. Dimethyl sulfoxide is used both in the spinning dope and in the coagulation bath.
