MSM is used as high-temperature solvent and raw material for organic synthesis, stationary liquid for gas chromatography and analytical reagent in industry. , food additives and drugs. MSM is a newly discovered human nutrient, which has therapeutic value and health care function for human diseases and is an essential drug for human survival and health care.
Developed countries attach great importance to it and widely use and sell it abroad. However, the application research of MSM in China has not been carried out. Therefore, the product department exports, while China has a large population, and MSM is a big country in production and export, which provides sufficient raw materials for MSM production.
Extended data:
The production method of dimethyl sulfone is mainly to oxidize dimethyl sulfoxide with nitric acid, that is, to oxidize dimethyl sulfoxide with nitric acid at 140- 145℃, cool after the reaction, and filter to obtain the crude product of white needle-like crystals.
Distilling under reduced pressure, and collecting the fraction of138-145℃ (98.42 kpa) to obtain the finished product.
Dimethyl sulfone should be stored in a cool and dry place, avoiding contact with skin and eyes and inhaling dust.
