Benzotriazole (BTA), identified by its CAS No. 95-14-7 and chemical formula C6H5N3, stands as a pivotal organic chemical compound widely recognized for its exceptional properties. This heterocyclic compound, appearing as a white solid, is formed by the fusion of benzene and triazole rings, giving it a unique molecular structure that contributes to its versatile applications across numerous industries. Its physical characteristics include a bitter taste and no discernible odor, with a boiling point around 204°C (at 15mmHg). BTA exhibits good solubility in organic solvents such as alcohol, benzene, and dimethylformamide, while being only slightly soluble in water, making it adaptable for various formulations and uses.

The primary and most significant application of Benzotriazole lies in its capacity as a highly effective corrosion inhibitor. It is particularly renowned for its ability to protect copper and copper alloys from degradation. When copper is exposed to a solution containing BTA, a robust and passive layer forms on the metal surface. This layer, a complex between copper and benzotriazole, is remarkably insoluble in both aqueous and many organic solutions. The effectiveness of this protective barrier is directly correlated with its thickness, offering superior long-term corrosion prevention.

Beyond its critical role in safeguarding metals, Benzotriazole finds extensive use in a multitude of other industrial and specialized applications. It is an indispensable component in antifreezing liquids, where it helps prevent corrosion within automotive and industrial cooling systems. As an antioxidant additive, BTA enhances the stability and performance of various oils, including lubricating oil, hydraulic oil, brake oil, and transformer oil, by mitigating oxidative degradation. Its properties also make it valuable as an emulsifying agent and a water stabilizer, contributing to the longevity and efficiency of systems that rely on water circulation.

Furthermore, Benzotriazole is integrated into high molecular materials such as polyester and polyesteramide to impart enhanced ultraviolet resistance and anti-static electricity capabilities, thereby extending the lifespan and functionality of these materials. In the photographic industry, BTA serves as a vital photographic antifogging agent or restrainer, ensuring clearer and sharper images by preventing unwanted fogging in emulsions and developing solutions. Its utility extends to mineral processing, specifically in copper mine flotation, where it aids in the separation of copper ores. Historically and in ongoing conservation efforts, BTA is also employed in heritage conservation for treating conditions like bronze disease, underscoring its broad utility.
