Sodium sulphate

General specification of Sodium Sulphate

Sodium sulphate, also known as sulfate of soda, is the inorganic compound with formula Na2SO4 as well as several related hydrates. All forms are white solids that are highly soluble in water.

Usage of sodium sulfate

odium sulfate, an inorganic compound with the formula Na2SO4, has various industrial applications due to its unique properties. Here are some common uses of sodium sulfate:

Detergent Manufacturing

Sodium sulfate is used in the manufacturing of powdered detergents. It helps control the viscosity of the detergent slurry and acts as a processing aid during the production of detergent powders.

Textile Industry

In the textile industry, sodium sulfate is employed in dyeing processes. It assists in leveling, or evenly distributing, the dye on the fabric, ensuring uniform coloration.

Paper and Pulp Industry

Sodium sulfate is utilized in the paper and pulp industry as a processing aid. It helps improve the efficiency of the kraft pulping process, which is used to separate cellulose fibers from wood.

Glass Industry

The glass industry uses sodium sulfate as a fining agent. It helps remove small air bubbles from molten glass, contributing to the clarity and quality of the final glass product.

Chemical Manufacturing

Sodium sulfate is a versatile compound in chemical manufacturing. It serves as a reactant in various chemical processes, including the production of sodium sulfide, sodium bisulfite, and other chemical compounds.

Textile and Leather Processing:

In addition to dyeing, sodium sulfate is used in the textile and leather industries for processes such as desizing, which involves removing sizing agents from fabrics.

Oil Recovery

Sodium sulfate is employed in enhanced oil recovery (EOR) methods. It can be injected into oil reservoirs to alter the water’s salinity, improving the efficiency of water flooding processes and aiding in the recovery of oil.

Food Additive

While not as common, sodium sulfate can be used as a firming agent in certain food products, helping to maintain the texture of the food.

Laboratory Applications

Sodium sulfate finds applications in laboratories as a drying agent for organic liquids. It is often used to remove traces of water from samples.

Deicing Agent

In some cases, sodium sulfate is used as a deicing agent on roads. While not as widely used as other deicing salts, it can help prevent the formation of ice under certain conditions.
