Sulfuric Acid

English Name: Sulfuric Acid

CAS No.: 7664-93-9

Molecular formula: H2SO4

Molecular weight: 98.07850

Purpose:

1. Metallurgy and petroleum industry

It is used in metallurgical industry and metal processing. Sulfuric acid needs to be used in the production process of metallurgical industry, especially non-ferrous metals. For example, when refining copper, zinc, cadmium and nickel by electrolysis, sulfuric acid is required for electrolyte. Sulfuric acid is also required for refining some precious metals to dissolve and remove other metals.

2. Solve the problem of people's basic necessities of life

Viscose silk, which is familiar to people in the production of chemical fiber, needs to use the mixture of sulfuric acid, zinc sulfate and sodium sulfate as the coagulation bath for viscose drawing.

3. Consolidate national defense

The development of sulfuric acid industry in some countries was once closely linked with the production of military explosives. Whether military explosives (propellants, explosives) or industrial explosives, most of them take nitrates or nitrates as their main components.

4. Atomic energy industry and rocket technology

The production of nuclear fuel for atomic reactors, the preparation of titanium, aluminum and other alloy materials for reactors, and titanium alloys used in the manufacture of rockets, supersonic jet aircraft and artificial satellites are directly or indirectly related to sulfuric acid.

5. Soil improvement

In agricultural production, sulfuric acid is increasingly used to improve calcareous soil with high pH value. Over the past 20 years, the yield of urea sulfuric acid fertilizer has increased significantly and is widely used in the soil of western states of the United States.

6. Fertilizer production

For the production of fertilizer, ammonium sulfate (commonly known as ammonium sulfate or Feitian powder) and calcium superphosphate (commonly known as lime superphosphate or calcium superphosphate) both consume a large amount of sulfuric acid.

7. Daily household use

Most acidic chemical channeling supplies around the world contain concentrated sulfuric acid. This kind of canal supplies, like alkaline canal supplies, can dissolve the oil and food residues clogged in the canal.
