The market quotation of 1,2,3-Benzotriazole

Introduction:
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 and alkaline aqueous solution,carbinol, 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.
Application:
1,2,3-Benzotriazole is mainly used in chemical industry. The 1,2,3-Benzotriazole is used as the original material of  silver,copper,zinc plating for the surface. It can form multilayer on the surface of copper,lead,iron,zinc and other metal materials to make the surface of the metal materials won’t have the redox reaction and be the corrosion protective role. And it also can cooperate with kinds of corrosion inhibitors to improve the effects of corrosion. And the 1,2,3-Benzotriazole can also be used with a variety of scale inhibitors. We often use it with germicide and algicide . The effect is very well when it is used for closed circulating cooling water system corrosion, especially in automotive antifreeze, ethylene glycol, water and coating to protect the materials. It also can be widely used in machinery industry. The 1,2,3-Benzotriazole can be used in the machining process. It can make the processing of copper invariant colour when add the BTA in grinding oil and cutting oil. 1,2,3-Benzotriazole can be used in photographic industry. The 1,2,3-Benzotriazole is used in antifogging agent and the intermediates of organic synthesis , the antifogging agent of black and white film and the photographic paper. We also use the 1,2,3-Benzotriazole in other branches of industry. The 1,2,3-Benzotriazole is the absorbent of the ultraviolet rays ,it’s the main category of lights stabilizer, it is used for plastic of resister,such as :Polyolefin, polyvinyl chloride, polystyrene, acrylic resin, polyester, polyamide, cellulose ester and so on. And it is also can be used as sun-screening agent. And the 1,2,3-Benzotriazole can prevent the diazo dyes fade ,you can process the paper with BTA, and it can prevent discoloration of braid,film,laminate metal coins and so on.
Marker quotation:
Copper has excellent strength, machining performance, electrical conductivity, the characteristics of weldability, corrosion resistance and other characteristics. For a long tome, it has been widely used in industry, military and civilian and other fields. But copper corrosion would happen under special circumstances. Therefore, the use of copper inhibitor for copper and copper alloy is very economic and effective way. As the copper corrosion inhibitor, 1,2,3-Benzotriazole can be adsorbed to form a thin film on the surface of metal, protect copper and other metals from corrosion of atmospheric and harmful medium. And it also can be used with a variety of scale inhibitor, biocide in circulating cooling water system,the circulating cooling water system corrosion effect is good. Its application will achieve greater results with the development of technology.
