1. Mordant: Sodium nitrite finds application as a mordant in the textile industry. It is used to enhance the dye absorption capacity of fabrics, ensuring better color fastness and improved dyeing results. By forming a complex with the dye molecules, sodium nitrite aids in achieving vibrant and long-lasting colors in textiles.

2. Bleaching agent: In various industrial processes, sodium nitrite acts as a bleaching agent. It is commonly employed in the production of paper and pulp, where it helps to remove impurities and brighten the final product. Additionally, sodium nitrite serves as a bleaching agent in the manufacturing of certain food products, such as cured meats, by preventing the growth of harmful bacteria.

3. Heat treatment agent: Sodium nitrite is extensively used as a heat treatment agent in metalworking industries. It plays a crucial role in the nitriding process, where it reacts with the surface of metals to form a hard nitride layer. This treatment enhances the durability, wear resistance, and corrosion resistance of metal components, making them suitable for various applications, including automotive and machinery parts.

4. Inhibitor: Sodium nitrite acts as an inhibitor in certain chemical reactions. It is particularly effective in preventing the corrosion of metals, such as steel, by forming a protective oxide layer on their surfaces. This property makes it valuable in industries where metal equipment and infrastructure are exposed to corrosive environments, such as oil refineries and chemical plants.

5. Reagent: Sodium nitrite serves as a reagent in various chemical reactions. For instance, it is utilized in the production of pharmaceuticals, dyes, and other organic compounds. Its ability to undergo reactions, such as diazotization, makes it a versatile and essential component in many synthesis processes.

6. Vasodilator: Sodium nitrite acts as a vasodilator, meaning it widens blood vessels, promoting improved blood flow. This property has medical applications, primarily in the treatment of certain cardiovascular conditions. Sodium nitrite can be administered under medical supervision to alleviate symptoms associated with conditions like angina and heart failure.

7. Material of chemicals: Sodium nitrite is widely used as a raw material in the production of various chemicals. It serves as a precursor in the synthesis of compounds like nitrosoamines, which find applications in the rubber and pharmaceutical industries. Furthermore, sodium nitrite is utilized in the manufacturing of corrosion inhibitors, antifreeze agents, and other specialty chemicals.

In summary, sodium nitrite is a versatile product with multiple application scenarios. Its functions as a mordant, bleaching agent, heat treatment agent, inhibitor, reagent, vasodilator, and material of chemicals make it indispensable in industries ranging from textiles and metalworking to pharmaceuticals and specialty chemicals.
