Product Description

Product Description

 

Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, colorless odorless transparent liquid at room temperature, and a hygroscopic flammable liquid.
With high polarity, high boiling point, good thermal stability, aprotic, and water miscible characteristics, can dissolve in ethanol, propanol, benzene and chlorofor m and other most organic matter, known as "universal solvent". In the presence of acid, heating will produce a small amount of methyl  mercaptan, methyl aldehyde, dimethyl sulfur, mesylate and other compounds. Decomposition phenomenon at high temperatures, chlorin e 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 a dye solvent, dye remover, dyeing carrier for synthetic fibers, as well as an absorber for recovering acetylene and sulfur  dioxide.
