Rui Desheng Chemical | Sodium Sulfate manufacturers [Tel] | Sodium Sulfate provided by 瑞德胜 chemical. We are Weifang Rui Desheng Chemical Co., Ltd. (www.ruidesheng.com) located at: Shandong Weifang specializes in: sodium sulfate, sodium metabisulfite, deicing salt, calcium chloride, baking soda, sulfuric acid is mainly used for making water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemistry reagents, pharmaceuticals. Tian Beach can be used, mechanical freezing, Salt Lake consolidation. Beach and mechanical field for freezing processed to Na, Mg, Cl, SO42-type water as a main component and other types of Glauber salt mines. Because the solubility of sodium sharply lower temperatures smaller equilibrium relationship can be separated from the brine in salt-water system in accordance with the crude Glauber Appearance: monoclinic sodium sulphate factory Tel, short prismatic crystals, aggregates showed a dense block like or hull shape, etc. Sodium Sulfate, colorless, transparent, sometimes with yellow or green, soluble in water. White, odorless, bitter crystalline or powder, hygroscopic. Appearance colorless, transparent crystals or granules larger small crystals. Structure: monoclinic, orthorhombic or hexagonal. Solution: a colorless solution sodium sulphate solution. Melting point: 884 ℃ (heptahydrate at 24.4 ℃ turn anhydrous, sodium sulfate decahydrate was 32.38 ℃ lowest, lost 10H2O at 100 ℃) Boiling Point: 1404 ℃ Relative density: 2.68g/cm3 thermodynamic functions (298.15K, 100kPa): standard molar heat of formation ΔfHmθ (kJ · mol): -1387.1 standard molar Gibbs free energy ΔfGmθ (kJ · mol ^ -1): -1270.2 standard entropy Smθ (J · mol ^ -1 · K ^ - 1): 149.6 Solubility: soluble in ethanol, insoluble in water, soluble in glycerin. Other properties: BaCl2 + Na2SO4 = BaSO4 ↓ +2 NaCl; sodium acid is oxygenated acid and alkali salts. Rui Desheng Chemical Co., Ltd. Weifang
