1. Food Preservation: Sodium nitrite is commonly used as a food preservative, particularly in cured meats such as bacon, ham, and sausages. It helps prevent the growth of bacteria, specifically Clostridium botulinu m, which can cause botulism. Sodium nitrite also gives cured meats their characteristic pink color and helps enhance their flavor.
2. Industrial Chemicals: Sodium nitrite is used in the manufacturing of various industrial chemicals. It is an important component in the production of nitric acid, which is used in the production of fertilizers, dyes, and pharmaceuticals. Sodium nitrite is also used in the production of other chemicals like diazo dyes, nitroso compounds, and corrosion inhibitors.
3. Heat Transfer Fluids: Sodium nitrite is used as a heat transfer fluid in some industrial processes. It has a high specific heat capacity and thermal conductivity, making it suitable for applications where heat transfer is required, such as in solar thermal systems and geothermal heat pumps.
4. Rust and Corrosion Inhibition: Sodium nitrite is used as a corrosion inhibitor in various industries, including automotive, oil and gas, and water treatment. It helps protect metal surfaces from rust and corrosion by forming a protective oxide layer.
5. Pharmaceutical Applications: Sodium nitrite is used in some pharmaceutical formulations. It can act as a vasodilator, helping to widen blood vessels and improve blood flow. It is used in the treatment of certain medical conditions like cyanide poisoning and methemoglobinemia.
Overall, sodium thiosulfate finds broad applications in industries such as photography, water treatment, medicine, and analytical chemistry.
