The product, High Quality benzotriazole with CAS number 95 - 14 - 7, is a well - recognized chemical compound in the industry. Benzotriazole is a heterocyclic organic compound with the molecular formula C₆H₅N₃. It appears as a white to slightly yellow crystalline powder.
The melting point of benzotriazole typically ranges from 96 - 99°C, and it has a boiling point of approximately 201°C at 15 mmHg. It has a relatively low solubility in water but is soluble in organic solvents such as ethanol, benzene, and toluene. The density of benzotriazole is around 1.36 g/cm³. This product is known for its high purity, which ensures its effectiveness in various applications.
1. Corrosion Inhibition: Benzotriazole is widely used as a corrosion inhibitor for copper and copper alloys. It forms a protective film on the metal surface, preventing oxidation and corrosion. In the electronics industry, it is added to plating solutions to protect copper components from environmental degradation, thus ensuring the long - term stability of electronic devices.
2. UV Absorber: It can absorb ultraviolet (UV) light, making it a valuable ingredient in sunscreen products and polymers. In plastics and coatings, the addition of benzotriazole can improve their weather resistance and prevent yellowing and degradation caused by UV radiation.
3. Photography: In the photography industry, benzotriazole is used as a stabilizer for photographic emulsions. It helps to prevent the fogging of photographic films and papers, improving the quality and clarity of the final images.
1. For Corrosion Inhibition: When using benzotriazole as a corrosion inhibitor for copper, it can be added to aqueous solutions at a concentration of 0.1 - 1% by weight. The solution should be thoroughly mixed to ensure uniform distribution of the compound. The metal surface should be cleaned before immersion in the solution to ensure good adhesion of the protective film. The immersion time depends on the application requirements, usually ranging from a few minutes to several hours.
2. As a UV Absorber: In polymers and coatings, benzotriazole can be mixed with the base materials during the production process. The recommended dosage is typically 0.5 - 2% by weight, depending on the specific polymer and the expected level of UV protection. The mixture should be well - dispersed to ensure effective UV absorption.
3. In Photography: In photographic emulsions, benzotriazole is added in small amounts, usually in the range of 0.01 - 0.1% by weight. It should be carefully dissolved in a suitable solvent and then added to the emulsion under controlled conditions to ensure proper incorporation and stability.
1. Electronics Manufacturer: An electronics manufacturer was facing corrosion issues with its copper - based circuit boards. After adding benzotriazole to the plating solution at a concentration of 0.5% by weight, the corrosion rate of the copper components was significantly reduced. The circuit boards showed improved performance and reliability over time, resulting in fewer product returns and increased customer satisfaction.
2. Plastic Product Manufacturer: A plastic product manufacturer was experiencing yellowing and brittleness in its outdoor plastic products due to UV radiation. By adding 1% benzotriazole to the plastic resin during the manufacturing process, the products exhibited better weather resistance. After a year of outdoor exposure, the color and mechanical properties of the plastic products remained relatively stable, and the market demand for the products increased.
3. Photography Studio: A photography studio was having problems with fogging on its photographic films. After adding 0.05% benzotriazole to the photographic emulsion, the fogging issue was effectively resolved. The images produced had better clarity and color accuracy, which improved the overall quality of the studio's work and enhanced its reputation in the market.
