Sodium sulphate CAS 15124-09-1 99% white in bulk

Chemical Composition: Sodium sulfate consists of sodium ions (Na+) and sulfate ions (SO4^2-). It is an inorganic salt that can exist in several hydrated forms, including anhydrous (without water) and hydrated (with water) variants.

Physical Properties: Anhydrous sodium sulfate typically appears as a white, odorless, crystalline solid. It is hygroscopic, meaning it can absorb moisture from the air. Hydrated forms of sodium sulfate contain varying amounts of water molecules within their crystal structure.

Purity: Sodium sulfate with a purity of 99% indicates that the compound is highly concentrated, with minimal impurities. This level of purity makes it suitable for various industrial applications where high-quality raw materials are required.

Industrial Applications:

• Detergent Manufacturing: Sodium sulfate is commonly used as a filler and processing aid in the production of powdered detergents. It helps to control the viscosity of detergent slurries and improves the flow properties of powdered formulations.
• Textile Industry: In the textile industry, sodium sulfate is used as a leveling agent and a dyeing assistant. It helps to evenly distribute dyes and chemicals during the dyeing process, ensuring uniform coloration of fabrics.
• Paper Industry: Sodium sulfate is employed in the paper industry as a pulping agent and bleaching auxiliary. It aids in the removal of lignin from wood pulp during the pulping process and enhances the brightness and strength of paper products.
• Chemical Synthesis: Sodium sulfate serves as a source of sodium ions and sulfate ions in various chemical reactions and industrial processes. It is used in the production of other chemicals, such as sodium sulfide, sodium carbonate, and sodium bisulfite.
• Glass Manufacturing: Sodium sulfate can be added to glass batches to modify the melting characteristics and improve the quality of glass products. It helps to reduce the viscosity of molten glass and prevent devitrification during the cooling process.

Desiccant: Anhydrous sodium sulfate has desiccant properties and is used to remove water traces from organic solvents and other liquid solutions. It is often employed in laboratory settings and industrial processes where moisture-sensitive materials are handled.

Environmental Considerations: Sodium sulfate is considered non-toxic and environmentally benign when handled appropriately. It is not classified as hazardous waste and can be disposed of safely in accordance with local regulations.

Safety Precautions: While sodium sulfate is generally safe to handle, precautions should be taken to avoid prolonged skin contact and inhalation of dust or vapors. Personal protective equipment, such as gloves and goggles, should be worn when handling large quantities of the compound.

Solubility: Sodium sulfate is moderately soluble in water. The solubility of sodium sulfate decreases with decreasing temperature, leading to the precipitation of anhydrous sodium sulfate from saturated solutions at lower temperatures. This property is utilized in certain industrial processes for the crystallization and purification of sodium sulfate.
