Sodium Sulphate Anhydrous (Na2SO4)

HS Code : 28331100 | CAS NO. : 7757-82-6

General description:

Chemical Formula: NA2SO4

  • Sodium sulfate anhydrous(na2so4) called Glauber Salt or sulfate of soda. It is chemically very stable and has an appearance of white crystalline solid. It has unsteady reaction towards most reducing or oxidizing agents at normal temperatures. In addition to this, it can be turned to sodium sulfide at high temperature by carbo-thermal reduction process.

  • The dry salt form of sulphuric acid is derived from Sodium sulfate anhydrous. All the forms of sodium sulfate have good solubility in water and white appearance.

  • The chemical compound's exact mass is 141.931268 g/mol and the molecular weight of sodium sulfate anhydrous is 142.04 g/mol.

Application & Usage:

  • In the textile industry, sodium sulfate anhydrous is used as a "leveling" agent which helps to decrease the negative charges on fibers. Its major role is as a filler in powder products, such as detergents.
  • Sodium sulfate anhydrous can be used as a binding and adhesive agent.
  • The adsorbents help to fix the molecules to the surface.
  • Farming and raising of crops.
  • Sodium sulfate anhydrous can be used in regulating the dyes.
  • Manufacturing glass, craft paper, and textile fabrics.
  • Sodium sulfate anhydrous is also used to produce medicines.

General Properties of Sodium Sulfate Anhydrous:
  • Sodium Sulfate Anhydrous chemical compound is generally present in white crystalline powder form.
  • Sodium Sulfate Anhydrous is also present physically in dry powder, pellets, large crystals, and wet solid.
  • The structure of the dry powder compound is orthorhombic bipyramidal crystals.
  • The particles are basically colourless crystals and are fine-white like a crystalline powder.
  • Odour- this chemical compound is mostly odourless.
  • Taste: this chemical compound is generally bitter saline in taste.
  • The melting point is 884 degrees Celsius.
  • The solubility in water is 28.1/100 grams of water at 25 degrees Celsius. It is also soluble in glycerine but is insoluble in alcohol. Overall, the solubility in water is very high.
  • The density of this chemical compound is 2.671.
  • The shelf life is good, but it is highly recommended to store it in the preferred conditions.
  • It emits the fumes of sodium oxide and sulphur oxides when they are heated in the decomposition process.
  • Corrosion: the corrosion rates depend on the mediums in which they are kept. It is slightly alkaline or neutral in nature.

Why is anhydrous sodium sulfate used in extraction?

During the extraction of chemical compounds, the organic layer always contains a certain amount of water in it. It is mostly used as a drying agent in many organic syntheses and it is also a dehydrating agent.

What is the function of sodium sulphate anhydrous?

The sodium sulfate anhydrous is mostly used as dying agents in many organic syntheses which is also a dehydrating agent because it instantly reacts with water to form sodium sulfate hydrate. It will remove a small amount of water from organic solutions and it can also be used to remove certain drugs from your body. It has prominent applications in soap and detergent, paper and pulp, glass industry, and textile industry.

How is sodium sulphate anhydrous removed from water?

Sodium sulfate anhydrous absorbs trace amounts of water when it is used in organic synthesis and mostly it presents as sodium sulphate with some amount of water. The sodium sulfate anhydrous manufacturers are treating that ester and nitrate to separate sodium sulfate anhydrous from water.

What is the function of sodium sulphate anhydrous in soap making?

The sodium sulphate anhydrous increases the quantity of the soap, because of its foaming capability. When sodium sulphate anhydrous is combined with sodium carbonate, the final quantity and quality of soap increases and hence is widely used for manufacturing soap.

How is sodium sulphate anhydrous stored?

The drying nature of sodium sulphate anhydrous prompts it to be stored in a tightly closed manner and in a dry place. It should be stored in a well-ventilated place that must be hygroscopic. It is a non-combustible solid so you should keep and store it well.
