High Quality N-Phenyl-1-naphthylamine with the CAS number 90 - 30 - 2 is a well - recognized chemical compound. It has a molecular formula of C₁₆H₁₃N and a molar mass of approximately 219.28 g/mol. Physically, it is often presented as a light yellow to brown flaky solid. This product is known for its high purity and excellent quality, meeting the strictest industrial standards. It has good solubility in organic solvents such as ethanol, benzene, and chloroform, but has relatively low solubility in water.
1. Rubber Industry: N - Phenyl - 1 - naphthylamine is an important antioxidant in the rubber industry. It can effectively prevent the aging and degradation of rubber products caused by heat, oxygen, and ozone. By adding this compound to rubber formulations, the service life of rubber products such as tires, rubber seals, and conveyor belts can be significantly extended. It protects the rubber from cracking, hardening, and loss of elasticity over time.
2. Lubricant Additive: In the field of lubricants, it serves as an anti - oxidant and anti - corrosion additive. It can enhance the oxidation stability of lubricating oils and greases, reducing the formation of sludge and varnish deposits. This helps to maintain the performance of engines, gears, and other mechanical components, improving their efficiency and reliability.
3. Petrochemical Industry: It is also used in the petrochemical industry as a stabilizer for some petroleum products. It can prevent the oxidation and polymerization of petroleum fractions during storage and transportation, ensuring the quality and stability of the products.
1. Rubber Compounding: When using it in the rubber industry, it is typically added during the mixing process. The recommended dosage usually ranges from 0.5% to 3% by weight, depending on the specific rubber formulation and the desired level of protection. The compound should be thoroughly mixed with other rubber ingredients to ensure uniform dispersion.
2. Lubricant Blending: For lubricant applications, it can be added to the base oil at the blending stage. The amount added is usually in the range of 0.1% to 1% by weight. It is important to heat the base oil slightly and stir continuously to ensure complete dissolution of the additive.
3. Petrochemical Products: In the petrochemical industry, it can be added directly to the petroleum products during production. The dosage is determined based on the characteristics and requirements of the specific products.
1. Tire Manufacturing Company: A leading tire manufacturer added N - Phenyl - 1 - naphthylamine to their tire rubber formulation. Before using this antioxidant, their tires had an average service life of about 30,000 kilometers under normal driving conditions. After adding 1.5% of this compound, the average service life of the tires increased to over 40,000 kilometers. This not only reduced the frequency of tire replacements for consumers but also improved the company's reputation for product quality.
2. Automotive Lubricant Manufacturer: An automotive lubricant company incorporated N - Phenyl - 1 - naphthylamine into their engine oil. In field tests, engines using the new lubricant showed less wear and tear on internal components compared to engines using the previous formulation. The oxidation stability of the oil was also greatly improved, allowing for longer oil change intervals. Customers reported smoother engine operation and better fuel efficiency.
3. Petrochemical Refinery: A petrochemical refinery used N - Phenyl - 1 - naphthylamine as a stabilizer for a certain petroleum fraction. During storage and transportation, the product without the stabilizer showed signs of oxidation and polymerization after a few weeks, resulting in changes in its physical and chemical properties. However, after adding the appropriate amount of this stabilizer, the petroleum fraction remained stable for several months, maintaining its original quality.
