Sodium benzotriazole is a chemical compound, specifically the sodium salt of benzotriazole, primarily used as a corrosion inhibitor and stabilizer in various applications. It is known for its ability to form a protective film on metal surfaces, particularly copper and other copper alloys, making it effective in systems like cooling towers and coolants.  Here's a more detailed breakdown: Key Properties and Uses:

• Corrosion Inhibition: Sodium benzotriazole is highly effective at preventing corrosion on metal surfaces, especially copper and copper alloys. 

Metal Protection: It forms a protective layer on the metal, reducing oxidation and extending the lifespan of components. 

Applications: It's used in: 

• Cooling water systems: As a corrosion inhibitor and scale inhibitor in cooling towers and other industrial water systems. 

Engine coolants: To protect engine components from corrosion. 

Metalworking fluids: As a corrosion inhibitor. 

Coatings and plastics: As a stabilizer and UV absorber. 

UV Absorption: It also has good UV-absorbing properties, which can help protect materials from photodegradation. 

Other Uses: It can also be used as an anti-discoloration agent, a coating additive, and a lubricant additive. 

Water Solubility: It is soluble in water, making it suitable for use in aqueous environments. 

Dosage: A typical dosage in circulating cooling water systems is 2-4 mg/L. 

Chemical Characteristics:

• CAS Number: 15217-42-2. 

Molecular Formula: C6H4N3Na. 

Clear, Yellow Liquid: It is often found as a clear, pale yellow liquid. 

40% Solution: A common form is a 40% solution in water, sometimes referred to as BTA40. 

Soluble in: Water, benzene, toluene, chloroform, and miscible with lower alcohols and ethylene glycol.
