Tolyltriazole can be used in different applications in major industries.
For example, it is used in cooling water or boiler systems by the industrial water treatment industry.
Tolyltriazole can be also used in coolants or antifreeze products.
Another application is the use as an additive in industrial lubricants, like e.g. drilling and cutting fluids.
Tolytriazole does also work to protect silver ware in dishwashing tablets and can be further used in metal detergents.

How does Tolytriazole work?

As a corrosion inhibitor, Tolyltriazole decreases the corrosion rate of metals and alloys.
This works by forming a coating, a passivation layer, which prevents access of the corrosive substance to the metal or alloy underneath.
This is of particular importance in industries where fluids routinely need to be in continuous contact with metals that require protection.

Tolyltriazole does show outstanding thermic and oxidative stability and is also resistant to UV light.
Tolytriazole does not negatively affect the appearance of the metal it's applied to.

Tolytriazole is very bright in color so that solutions – either aqueous or in different solvents – are clear and almost colorless.
A table of solubility properties and max concentrations is available on request.

Tolytrizole is an effective corrosion inhibitor for copper and copper alloys.
Tolytriazole works by adhering to the surface of copper and forming a strong electrochemical barrier that is a few molecules thick to protect against attacks by corrosive ions.
The protective barrier is not easily removed and shows a high degree of thermal and oxidative stability.
In solution, Tolyltriazole complexes copper to protect against galvanic corrosion by other metals.
Although structurally similar to benzotriazole, the extra methyl group of Tolyltriazole aids in solubility in some organic solvents.
Tolytriazole is commonly used in applications such as circulating water cooling systems, runway deicer, brake and hydraulic fluids, automotive coolants, metalworking fluids, and other specialty lubricants.

Although zinc has protective effect on steel, it is also needed to apply other measures to improve the corrosion resistance of galvanized steel since zinc layer is normally thin.
Recently, researchers have attempted to use corrosion inhibitors to protect galvanized steel, which restrains zinc from the formation of white corrosion products in the corrosive media Tolytriazole.
Literature has reported that some organic molecules with hetero-atoms (such as oxygen, nitrogen, sulphur and so on) can serve as corrosion inhibiting agents, which may be adsorbed on the surface of metals or react with metals to generate undissolved and stable metal complexes.
Tolytriazole-type organic compounds, especially benzotriazole, including nitrogen are particularly used as corrosion inhibitors for copper, cast iron, zinc and so on.
Benzotriazole, which has low toxicity and is economical, finds use as a good corrosion inhibitor.

Corrosion inhibition of copper by tolytriazole (TTAH) in comparison with benzotriazole (BTAH) was investigated in unpolluted and sulfide polluted 3.5 % NaCl.
Both Tolytriazole and BTAH give approximately similar results in unpolluted salt water.
Electrochemical techniques illustrate that Tolytriazole gives about (40%) higher efficiency than BTA in case of sulfide polluted media.
Surface analysis by X-ray photoelectron spectroscopy reveals the presence of both sulfide and Tolytriazole on the corroded surface.
In sulfide polluted salt water Tolytriazole shows better performance than BTAH.
The mechanism of protection is attributed to the formation of protective film of Tolytriazole or BTAH.
The rate of destruction of the protective film in Tolytriazole is lower than that of BTAH in the presence of sulfide ions.
This result is established at sulfide concentration as low as 10 -3 M in the presence of 10 -2 M Tolytriazole.
The gained results prove that Tolytriazole gives better resistance against sulfide attack.
