Anhydrous sodium sulfate

Anhydrous sodium sulfate

Sodium sulfate is a salt formed by the combination of sulfate ions and sodium ions, with the chemical formula Na2SO4. Sodium sulfate is soluble in water, and its solution is mostly neutral, soluble in glycerol but insoluble in ethanol. Inorganic compounds, high-purity, fine-grained anhydrous substances are called yuanming powder. Yuanming powder is a white, odorless, bitter crystalline or powder with hygroscopic properties. The appearance is colorless, transparent, large crystals or granular small crystals. Sodium sulfate easily absorbs water when exposed to air, forming sodium sulfate decahydrate, also known as mirabilite, which is slightly alkaline. Mainly used for manufacturing water glass, glass, enamel, pulp, refrigeration mixtures, detergents, desiccants, dye diluents, analytical chemical reagents, pharmaceuticals, feed, etc. At 241 ℃, sodium sulfate will transform into hexagonal crystals. Sodium sulfate is the most commonly used post-treatment desiccant in organic synthesis laboratories. Upstream raw materials include sulfuric acid, caustic soda, etc.
