English Name: 1H-Benzotriazole
CAS No.: 95-14-7
Molecular formula: C6H5N3
Molecular weight: 119.12
Chemical properties: colorless acicular crystal. Slightly soluble in cold water, ethanol and ether.
Application: benzotriazole is mainly used as water treatment agent, metal rust inhibitor and corrosion inhibitor. Benzotriazole is one of the most effective corrosion inhibitors for copper and copper alloys in cooling water system. It is widely used in circulating water treatment agent, antirust oil and lipid products, as well as vapor phase corrosion inhibitor and lubricating oil additive of copper and copper alloy. In electroplating, it is used to purify silver, copper and zinc on the surface, which can prevent discoloration.
