What is 1,2,3-Benzotriazole?


The introduction of 1,2,3-Benzotriazole:
1,2,3-Benzotriazole is also named BTA. The chemical formula of the 1,2,3-Benzotriazole is C6H5N3. The appearance of 1,2,3- Benzotriazole is needle crystal powder of white to pale pink,odorless,it is slightly soluble in cold water but it can be soluble in hot water andalkaline aqueous solutioncarbinol, ethanol, diethyl ether, acetone, benzene, methylbenzene, chloroform and dimethyl formamide. The 1,2,3-Benzotriazole gradually become red when it is placed in the air. A explosion can occur when it is in a vacuum distillation.
It is mainly used for metal (such as silver, copper, lead, nickel, zinc) rust inhibitor and corrosion inhibitor, is widely used for the anti rust oil (grease) products, used for copper and copper alloy gas phase corrosion inhibitor, water treatment agent, antifreeze, anti fog agent, polymer film dust plant growth regulator, stabilizer, lubricant agent, ultraviolet absorbent. This product can with various scale inhibitor, biocide use, especially for the closed cycle cooling water system corrosion inhibition effect is very good.
1,2,3-Benzotriazole is one of the most commonly used in copper and copper alloy corrosion inhibitor, to form a layer of insoluble stable film and cuprous ion of copper metal surface, electrochemical corrosion preventing dissolved oxygen, its corrosion resistant performance is also effective on aluminum zinc metal, stable chemical property, good thermal stability, no solution. Compound and organic phosphonic acid, polymer and other products, the corrosion inhibitor in circulating water containing copper equipment used for copper and copper alloy, corrosion is particularly suitable for power plant condenser and central air-conditioning condenser copper material.
The performance and characteristics of 1,2,3-Benzotriazole:
It is a kind of corrosion inhibitors which has a excellent effect on metals.
The reduction of it to acid, alkali and oxidant are very stable.
It can generate stable metal salts with alkali metal ions.
It has good thermal stability.
Packaging and storage:
The packaging of 1,2,3-Benzotriazole should be hermetic sealing,cannot get touch with air, or it may form explosive mixture when mixed with air. And you should keep it dry,and avoid it contact with combustible material.
