Introduction to Sodium Sulfate BP


Sodium Sulfate is the sodium salt of sulfuric acid. It appears as an anhydrous, decahydrate, and heptahydrate forms. When anhydrous, it is a white crystalline solid of formula Na2SO4 known as the mineral thenardite. When it appears as decahydrate, it has formula of Na2SO4·10H2O. When it is cooled, it appears as heptahydrate. It is usually stays stable. Sodium Sulfate BP can be produced naturally or chemically. When it is naturally produced, it is usually found in Great Salt Lake. When it is chemically produced, it is usually reacted with other chemicals. Sodium Sulfate BP is usually used for making detergents, textiles, heat storage, and others.
Because of its moiture-adsorbing ability, the anhydrous salt is used for drying certain organic liquids. The loose, granular anhydrous solids changed to the hydrated from which is lumped together. Sodium Sulfate BP also applies in the manufacture of glass, paper pulp, paper board, and as a raw material for the production of various chemicals. For example, in the kraft process for paper making, non-cellulose parts of the wood (such as lignin) are removed by heating the wood pulp with an alkaline solution of sodium sulfide at 170°C for three hours. What’s further, Sodium Sulfate BP acts as a filler and extender in dry powder, laundary and dishwashing detergent products. In textile industry, the anhydrous salt is added to the dyebath to drive the dye from the solution onto the fibres and to promote an even finish.
