Anhydrous sodium sulfate, also known as sodium sulfate, is a widely used raw material in the field of chemical production. In the chemical industry chain, there are many upstream and downstream related products of anhydrous sodium sulfate. This article will detail the upstream and downstream associated products of anhydrous sodium sulfate.

upstream products

1. sulfuric acid: sulfuric acid is the main raw material for the production of anhydrous sodium sulfate. Anhydrous sodium sulfate can be produced by reacting sulfuric acid with sodium hydroxide or trona.
2. Sodium hydroxide: Sodium hydroxide reacts with sulfuric acid to produce anhydrous sodium sulfate and water.
3. Trona: Trona can also react with sulfuric acid to produce anhydrous sodium sulfate.

production equipment

anhydrous sodium sulfate production equipment mainly includes reaction kettle, centrifuge, dryer and so on. The reactor is used to react the raw materials, the centrifuge is used to separate the product and the mother liquor, and the dryer is used to remove the moisture in the product.

production process

anhydrous sodium sulfate production process mainly includes reaction, centrifugal separation, drying and other steps. Specifically, sulfuric acid and sodium hydroxide or trona are added into the reaction kettle according to a certain proportion, and a certain temperature and reaction time are controlled to generate anhydrous sodium sulfate and water. Then, the anhydrous sodium sulfate and the mother liquor were separated by a centrifuge, and finally the product was dried using a dryer.

Downstream Products

1. Detergent: Anhydrous sodium sulfate can be used as the main component of detergent, with decontamination, emulsification, dispersion and other functions.
2. Glass manufacturing: Anhydrous sodium sulfate can be used as a flux in glass manufacturing to help reduce the melting temperature of glass and improve glass production efficiency.
3. Chemical analysis reagent: Anhydrous sodium sulfate can be used as a chemical analysis reagent for the determination of chloride ion content in water.
4. pharmaceutical intermediates: anhydrous sodium sulfate can be used in the production of certain pharmaceutical intermediates, as raw materials for the production of raw materials.

application field

anhydrous sodium sulfate is widely used in chemical industry, light industry, medicine, textile, printing and dyeing, papermaking, food and other industries. Specifically, anhydrous sodium sulfate can be used as detergent, dyeing agent, heat preservation agent, preservative, coagulant, fluffing agent, etc. In the pharmaceutical industry, it can be used as laxative and antidote for barium salt poisoning, etc. In the chemical industry, it can be used to manufacture chemical raw materials such as sodium sulfide and sodium silicate (water glass). In the mining industry, it can be used as a flux to extract chloride; in the fertilizer industry can be used as phosphate fertilizer filler.

In general, as an important chemical raw material, anhydrous sodium sulfate has a wide range of applications in the field of chemical production. Its upstream and downstream related products are numerous, involving a wide range of applications.
