Tolyltriazole is a chemical compound which is known by C7H7N3 as its chemical formula. Tolyltriazole is commonly used for the commercial combination consisted of nearly the same amounts of 4- and 5-methyl benzotriazole with a small content of the 6- and 7- methyl isomers. this chemical component is grouped in heterocyclic compounds. This component is also known by these names, Methylbenzotriazole and Methyl-1H-Benzotriazole.
Physical and Chemical properties of TTA:
It is difficult to dissolve in water but it is also soluble in organic solvents such as toluene, chloroform, and alcohol. When copper is immersed in a solution of triazole toluene, a complex form on the surface of the copper, which is an unreactive, resistant, and insoluble layer in water and many chemical solvents, preventing corrosion and rusting of copper and its alloys.
tolyl triazole can also be used as an anti-corrosion agent in cooling systems, the structure of this aromatic chemical is very sensitive to heat and rising temperatures can cause them to decompose.
Triazole tolyl is a benzotriazole derivative to which a methyl group has been added to the benzene ring. This methyl substitution on the benzene ring has made the methyl group an effective compound in controlling the corrosion of copper and its alloys due to its hydrophobicity.

Synthesis and Production Process of Tolyl triazole (TTA):
The production of this aromatic compound cannot be done with oxidizing agents because it neutralizes acids in the chemical reaction and this neutralization causes the production of salt with water.
The synthesis of tolyl triazole can be done in a round bottom container that temperature can be measured. To perform this exothermic reaction, we need a stirrer, a funnel, and a nitrogen gas inlet pipe, such as a condenser.
This reaction is carried out by a certain amount of hexanol with toluene diamine. To start the synthesis, wrap the reaction vessel with tin foil and heat it to a temperature of about 90 ° C, and add ethyl hexyl nitrate to the solution within 30 minutes. we do. Bring the above solution to a temperature of 120 ° C and then add some sodium hydroxide to it.
We heat the solution again with a separating funnel and a small amount of charcoal, and after filtration, cooling, and, of course, crystallization operations, we can obtain the desired product.

Application and Uses of tolyl triazole (TTA):
tolyl triazole is a water-stabilizing chemical that prevents corrosion by attaching to metal parts and machine surfaces. It can chemically create an electrochemical barrier that is thick enough to contact corrosive chemicals.
Triacyl granules are adsorbed on the surface of the metal and prevent the corrosion of metals against air by forming a thin membrane. The presence of this chemical in the medium prevents the reaction between free hydrogen ions and the surface of aluminum and can prevent the oxidation reaction of aluminum.
This chemical is also used in the water treatment industry or the production of antifreeze for cars, plant growth regulators, lubricants, and additives or UV absorbers.
Triazole tolyl powder has a good anti-corrosion effect in rotary water-cooling systems, which is combined with antibacterial and algal agents.
In internal combustion engines, combustion of air and fuel occurs inside the engine cylinder and as a result of this combustion, very hot gases with a temperature of about 2300-2500 ° C are produced. Due to the high temperature of the combustion, there is a possibility of burning the oil layer between the moving parts and as a result, the engine will stop or boil.
The temperature at which the engine can run at its most efficient is about 150-200 ° C. If the engine temperature drops more than this amount, problems such as faster wear on engine components and the production of more pollutants will occur.
since controlling the temperature of the liquid flowing in the engine is very important, it has been tried to create better control over the temperature of the liquid inside the engine with the help of a coolant. Various solutions are added to the engine as a coolant, and triazole is one of the chemicals that can be used as an antifreeze for cars.
Before using tolyl triazole, it is necessary to carefully study its MSDS and use gloves, masks, and other safety equipment. This compound can cause respiratory problems and inhalation can damage the respiratory system and lungs. Exposure to this substance can cause eye and skin irritation, so it is necessary to have an active ventilation system when using this substance or to do it under the hood with safety tips.
Transporting and Storage:
It is recommended to store this material in closed containers upright and in a dry and cool environment, with proper ventilation and away from sunlight and heat sources such as fire.
