Product Description
Dimethyl sulfoxide (DMSO)is a sulfur-containing organic compound, the molecular formula is C2H6OS, at room temperature is colorless odorless transparent liquid, is a hygrometric flammable liquid. With high polarity, high boiling point, good thermal stability, aprotic, and water miscible characteristics, can dissolve in ethanol, propanol, benzene and chloro-form and other most organic matter, known as "universal solvent". In the presence of acid, heating will produce a small amount of methyl mer-captan, formaldehyde, dimethyl sulfur, mesylate and other compounds. Decomposition phenomenon at high temperatures, chlo-rine can occur violent reaction, burning in the air issued a light blue flame. It can be used as organic solvent, reaction medium and intermediate of organic synthesis. It can also be used as dye solvent, dye remover, dye carrier and absorbent for recovering acetylene and sul-fur dioxide of synthetic fibers.
