Product Name:Sodium Sulfate
Product Description:
Description:Sodium sulfate is an important chemical raw material. It is the main raw material for the production of chemical products such as sodium sulfide and sodium silicate. It can also be used as a filler for synthetic detergents and as a cooking agent for the manufacture of kraft pulp in the paper industry.Sodium sulfate is also called Yuanming powder, anhydrous thenardite, and anhydrous skin nitrate. White monoclinic fine crystal or powder. The relative density is 2.68 and the melting point is 884 °C. Dissolved in water, the aqueous solution is neutral. Soluble in glycerin, insoluble in ethanol, exposed to air, easy to absorb water into aqueous sodium sulfate. It is a homogeneous polycrystalline material having a rhomboid shape at a temperature of 32.4 to 223 ° C. At a higher temperature, a monoclinic crystal is formed, and 241 ° C is converted into a hexagonal crystal. When crystallizing from solution, it has affinity for iron, iron compound and various organic substances; high-purity, fine-particle anhydrous sodium sulfate is called Yuanming powder.Melting point884 °C(lit.)Boiling point1700°CDensity2.68 g/mL at 25 °C(lit.)Refractive index1.484Storage conditionsStore at RT.SolubilityH2O: 1 M at 20 °C, clear, colorlessformpowder (fine)colourWhitePH value5.2-8.0 (50g/l, H2O, 20℃)Water solubility18.5 mg/LSensitivityHygroscopicMerck14,8680stabilityStable. Incompatible with strong acids, aluminium, magnesium, strong bases. Hygroscopic.CAS database7757-82-6(CAS DataBase Reference)The main purpose: Sodium sulfate is an important raw material for the manufacture of glass and paper. It is the most used in the paper and cellulose industry and accounts for about 70% of the total. Sodium sulfate is a component of a synthetic detergent which is a neutral salt which is added to reduce surface tension and increase the solubility of the detergent. It is also a thinner for dyes and an auxiliary for dyeing and dyeing. It is used as a dyeing agent for dyeing cotton fibers such as direct dyes, sulphur dyes and vat dyes. It is used as a retarder for dyeing silk directly. Sodium sulfate is used as a raw material in the chemical industry for the manufacture of sodium sulfide, gypsum, sodium silicate and other chemical products. Methods for the manufacture of sulfuric acid, sulfur, soda ash, ammonium sulphate and other products with sodium sulphate have been developed, but these methods are currently not costly due to their high cost. Sodium sulfate cold agent is commonly used in laboratories. Medical Glauber's salt is used as a laxative. Most of the sodium sulfate that enters the body stays in the gastrointestinal tract, is not absorbed, and maintains a certain penetration, which can increase the intestinal contents and cause intestinal peristalsis, and has a diarrhea effect. Sodium sulfate is an antidote to bismuth and lead poisoning. When lead poisoning, gastric lavage with 10% Glauber's salt or oral administration of 1-2% sodium sulfate solution can be used.
