Sulfuric acid plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following will detail the upstream and downstream associated products of sulfuric acid.

upstream product

1. Sulfur: the main raw material of sulfuric acid is sulfur. Sulfur generates sulfur dioxide through combustion reaction, and then finally generates sulfuric acid through oxidation, absorption and other processes.
2. Pyrite: Pyrite is another raw material for sulfuric acid production, its main component is ferrous disulfide (FeS2), after calcination, oxidation, absorption and other processes to generate sulfuric acid.

downstream products

1. phosphate fertilizer: sulfuric acid and phosphate rock reaction can generate phosphoric acid, and then produce phosphate fertilizer, such as superphosphate, compound fertilizer and so on. Phosphate fertilizer plays an important role in plant growth and helps to improve crop yields.
2. Nitrogen fertilizer: Sulfuric acid can react with ammonia to produce ammonium sulfate, and then produce nitrogen fertilizer. Nitrogen fertilizer has a promoting effect on plant growth and can increase the protein content of crops.
3. Hydrochloric acid: Sulfuric acid can react with sodium chloride to form sodium sulfate and hydrochloric acid. Hydrochloric acid has a wide range of applications in industrial production and laboratories, such as metal processing, inorganic chemical products production, etc.
4. Titanium dioxide: Sulfuric acid can react with ilmenite to produce titanium sulfate, which in turn produces titanium dioxide. Titanium dioxide is an important inorganic pigment, with excellent weather resistance, light resistance, heat resistance and other properties, widely used in coatings, plastics, paper and other industries.

In short, the upstream and downstream related products of sulfuric acid in the field of chemical production raw materials are very extensive, which plays an important role in promoting the development of agriculture, industry and other fields.
