1,2,3-BENZOTRIAZOLE CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES

1,2,3-Benzotriazole is an aromatic heterocyclic compound consisting of a benzene ring fused with a 1,2,3-triazole ring. Its molecular formula is C₆H₅N₃ and its molecular weight is approximately 119.12 g/mol.

The three nitrogen atoms in the Benzotriazole molecule play an important role in its electronic properties and interaction with metal surfaces.

The solubility of 1,2,3-Benzotriazole in water is one of the properties that enables its use in aqueous corrosion inhibitor formulations. Scientific studies have reported water solubility at approximately 20 g/L; the actual solubility value should be evaluated according to temperature, purity and measurement conditions.

The primary function of Benzotriazole as a corrosion inhibitor is associated with adsorption onto metal surfaces, particularly copper surfaces, and the formation of a protective surface layer.

The presence of Benzotriazole on copper surfaces can help limit metal dissolution reactions and contribute to the formation of a more protective surface layer. Research associates the protective effect of BTA on copper and copper alloys with surface adsorption and the formation of a Cu-BTA-related protective film.

HOW DOES 1,2,3-BENZOTRIAZOLE WORK AT THE MOLECULAR LEVEL?

When 1,2,3-Benzotriazole dissolves in water or a suitable formulation medium, it can reach the metal surface and exhibit adsorption, particularly on copper-containing surfaces.

The binding of Benzotriazole molecules to the copper surface can help establish a relationship between the metal and a protective surface layer.

This surface layer can limit copper dissolution and its interaction with surrounding corrosive species, thereby contributing to a reduction in the corrosion rate.

The primary functions of 1,2,3-Benzotriazole as a corrosion inhibitor include:

Helping protect copper surfaces

Supporting corrosion control in copper alloys

Contributing to the reduction of metal dissolution reactions
