Sodium nitrate is an important inorganic chemical raw material, which is widely used in various fields. In the field of raw materials for chemical production, the upstream and downstream related products of sodium nitrate mainly include the following categories:

upstream products:

1. Nitric acid: Nitric acid is one of the main raw materials for the production of sodium nitrate, which is produced by the neutralization reaction of nitric acid and sodium hydroxide.

2. sodium hydroxide: sodium hydroxide is also one of the main raw materials for the production of sodium nitrate, the same through the neutralization of nitric acid and sodium nitrate.

downstream products:

1. Sodium nitrite: Sodium nitrate can be converted into sodium nitrite through a reduction reaction. Sodium nitrite is an important food additive and industrial raw material.

2. potassium nitrate: sodium nitrate can react with potassium chloride to produce potassium nitrate, potassium nitrate is an efficient fertilizer and gunpowder raw materials.

3. nitrate mixture: sodium nitrate can be mixed with other nitrates to make nitrate mixture, used in the manufacture of gunpowder, glass, ceramics, etc.

4. Nitrogen oxides: Sodium nitrate can be used as a nitrogen source to generate nitrogen oxides through thermal decomposition or reduction reactions, which are used in the manufacture of nitrogen compounds and environmental protection.

In short, sodium nitrate, as an important chemical raw material, has a wide range of upstream and downstream related products in the field of chemical production raw materials, and plays an important role in promoting the development of the chemical industry.
