BTA is a chemical substance with the molecular formula C6H5N3. Benzotriazole is mainly used as a water treatment agent, metal rust inhibitor and corrosion inhibitor. It is widely used in circulating water treatment agents, anti-rust oils, and lipid products. It is also used in copper and copper alloy vapor phase corrosion inhibitors and lubricant additives. It is used to passivate the surface of silver, copper, and zinc in electroplating to prevent discoloration. It is a white light brown needle-shaped crystal that can be processed into flakes, granules, and powders. It gradually turns red when oxidized in the air. It tastes bitter and odorless. It can explode when distilled in a vacuum. It is soluble in ethanol, benzene and N,N-dimethylformamide, and slightly soluble in water.
