Usage: DMSO is widely used as solvents and reagents, in particular, for processing of acrylonitrile polymerization solvent and snag solvent for polyurethane synthesis and snag solvent for polyamide, polyimide, and polysulfone resins synthetic solvents, as well as aromatics, butadiene extraction solvents and synthetic chlorofluorocarbon solvents such as aniline. In addition, dimethyl sulfoxide in the pharmaceutical industry, there are certain drugs directly used as raw materials and carriers. DMSO itself has anti-inflammatory analgesic, diuretic, sedative and other effects, but also as the "panacea", often as a pain medicine active ingredients of drugs being added to.
