Sodium sulfate
Sodium sulfate (CAS: 7757-82-6, Na₂SO₄) is an inorganic salt supplied by Tech Serve Solutions as a white crystalline powder. With a molecular weight of 142.04 g/mol and an assay of ≥99.0%, it serves as a foundational reagent in chemical synthesis. Its applications span various industrial processes, including its use in the manufacture of detergents, glass, and textiles. This essential chemical is a reliable component for research and industrial applications requiring high purity.
Detergent Manufacturing
Sodium sulfate acts as a filler and processing aid in powdered laundry detergents, helping to improve flowability and prevent caking. It contributes to the overall bulk of the detergent formulation.
Glass and Pulp Industries
In glass production, it serves as a fining agent, removing small bubbles and improving clarity. Within the Kraft process for papermaking, it is a source of sulfur for chemical recovery.
Chemical Synthesis
As a readily available source of sulfate ions, sodium sulfate is employed in various inorganic and organic synthesis reactions. It is also used as a drying agent in organic chemistry, though less common than other desiccants.
Textile Dyeing
It is utilised in the textile industry as a levelling agent in dyeing processes, particularly with cellulosic fibres. Sodium sulfate helps to ensure even dye uptake and prevent uneven coloration.
