Sulfoxide solvent has a high dissolving capacity for aromatics, good selectivity, good thermal stability, low vapor pressure, low toxicity and no corrosion to carbon steel. Therefore, sulfoxide extraction technology has become the most widely used aromatics extraction technology in the world at present.
Colorless and odorless solid, melts into colorless and transparent liquid at 27 to 28 degrees Celsius. It is miscible with water, mixed xylene, methyl mercaptan and ethyl mercaptan, and also soluble in aromatic hydrocarbons and alcohols.
It is used as a stationary liquid and analytical reagent in gas chromatography, and also in organic synthesis
It is a polar solvent with strong solubility and good selectivity. Most organic compounds and polymers can be dissolved in sulfoxide or miscible with it. It is mainly used as an extractant for aromatic hydrocarbon extraction, a solvent for polymer spinning or film casting, for the purification of natural gas, syngas and refinery gas, for the purification and desulfurization of syngas, and as a solvent for rubber and plastics, etc. In addition, Chemicalbook can also be used in the textile printing and dyeing industry as a printing and dyeing assistant, which can make the colors bright and lustrous. Sulfoxide solvent has a high dissolving capacity for aromatics, good selectivity, good thermal stability, low vapor pressure, low toxicity and no corrosion to carbon steel. Therefore, sulfoxide extraction technology has become the most widely used aromatics extraction technology in the world at present.
It is used for the purification and desulfurization of natural gas, the extraction of aromatics from reformed oil, and the removal of impurities such as carbon dioxide, hydrogen sulfide and organic sulfur in hydrogen
An efficient and multi-purpose solvent; Gas chromatography stationary liquid (maximum operating temperature 100℃, solvent acetone), for the separation and analysis of low-grade hydrocarbon isomers; It is used as a selective solvent for gas-liquid extraction to extract aromatic hydrocarbons from aliphatic hydrocarbons and remove acidic gases from gas mixtures
