What is 1H-Benzotriazole ?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 1H-Benzotriazole which has developed particularly rapidly in recent years. Do you know about 1H-Benzotriazole?
- The official answer：Colorless needle-like crystals. Slightly soluble in cold water, ethanol, ether, melting point 97-99 °C (lit.) boiling point 204 °C (15 mmHg) density 1,36 g/cm3 vapor density 4.1 (vs air) vapor pressure 0.04 mm Hg ( 20 °C) refractive index 1.5589 (estimate) flash point 170 °C.
What’s the application of 1H-Benzotriazole ?
- Benzotriazole is mainly used as a 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 systems. It is widely used in circulating water treatment agents, rust preventive oil, and grease products, and is also used as a vapor phase corrosion inhibitor and lubricant additive for copper and copper alloy. It is used in electroplating to purify silver, copper, and zinc on the surface and has an anti-discoloration effect. It is used in lubricating oil and grease such as extreme pressure industrial gear oil, double curve gear oil, anti-wear hydraulic oil, oil film bearing oil, grease, etc. It can be used as an antirust and vapor phase corrosion inhibitor. This product can also be used with a variety of scale inhibitors, algaecides. It is widely used for corrosion inhibition and rust prevention of copper and silver equipment. It can also be used in the preparation of photographic anti-gray and anti-fogging agents and gas-phase antirust agents. It is used in electroplating to purify silver, copper, and zinc on the surface and has an anti-discoloration effect. Benzotriazole (BTA) forms covalent and coordination bonds with copper atoms, and mutually multiply into chain-like polymers, forming a multilayer protective film on the surface of copper plus, so that the surface of copper does not have a redox reaction, and no hydrogen occurs, which plays a role in corrosion prevention. BTA can be used with a variety of corrosion inhibitors to improve the corrosion inhibition effect. BTA can also be used with a variety of scale inhibitors, algaecides, especially for closed circulating cooling water system corrosion inhibition effect is very good, in the automotive antifreeze glycol and water, paint added BTA can volatile protection of the material role. BTA can prevent discoloration of paper, woven fabrics, films, metal coins, and other thin products. In the process of mechanical processing, BTA will be added to the grinding oil, cutting oil, can make the processed copper parts do not change color. The product can also be used as an analytical reagent, and ammonia and diamine tetraacetic acid together can be used for the selective determination of silver, copper, zinc. It can also be used as a photographic anti-grey fogging agent and organic synthesis intermediate.
