Benzotriazole (BTA)

Benzotriazole (BTA) is a chemical compound which is known by C6H5N3 as its chemical formula. because it has atoms of at least two different elements as members of its ring(s). This chemical component is grouped in heterocyclic compounds. This component also known by these names: 


chemical formula:


This compound is an odorless, crystalline powder and can be utilized in a various range of applications. Three kinds of material involve in BTA reaction: o-phenylenediamine, sodium nitrite, and acetic acid. In lower temperature about 5 to 10 ˚C the synthetic reaction can be ameliorated.

Benzotriazole applications

Although this chemical compound has a lot of uses in many industries but the most prevalent application is impeded metals against corrosion particularly for copper. Copper due to its various application in various ranges of industries is exposed to corrosion. To prevent this effect Benzotriazole used as a barrier film to hamper metals due to corrosion and damaging. This function is operational for many types of equipment that are pertinent to water like cooling water systems. For other metals like aluminum, it has its Corrosion prevention application too. When Benzotriazole applied on the surface of the metal it does not change its appearance. It is just a top coat to prevent damaging and doesn’t have any other effects for the metal. Benzotriazole has been famous for its excellent conformity and a reagent for the analytical specification of silver. BTA can be used as antifreeze, heating and cooling systems, hydraulic fluids and vapor phase inhibitors as well.


Environmental impact and issues

As a matter of environmental issues, Benzotriazole is forcefully stable in natural environments like water and soil. And a small amount of it may prevent plants growth. They may decompose by the Fenton reactions. This compound is partially released from wastewater treatment plants and a considerable portion reaches surface water such as rivers and lakes, as a result, this chemical component should not be released into the environment. Keep in suitable, closed containers for disposal in Laboratory scale and treated before Released in the environment on an industrial scale. Dispose of container to an approved waste disposal plant in order to Non-release in the environment.

Benzotriazole main safety data

Personal discretion
Ensure sufficient ventilation, use personal accouterments and avoid dust formation.


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 also known by these names:


Tolyltriazole application

Tolyltriazole is used as an inhibitor of corrosion of copper and copper alloys. Also, it used as antirust additives of metals. This compound doesn’t have any influence on metals appearance, conductivity, and electricity.
These two compounds can bring in one data sheet because their application is almost the same but their chemical structure and appearance is Different.
