High Quality 2-Ethylhexyl Diphenyl Phosphite with the CAS number 15647-08-2 is a chemical compound known for its high - quality and low price. This product typically comes in a clear, colorless to pale - yellow liquid form. It has a molecular formula of C₂₀H₂₇O₃P and a molecular weight of approximately 346.4 g/mol.
The density of 2 - Ethylhexyl Diphenyl Phosphite is around 1.05 - 1.07 g/cm³ at 25°C. It has a boiling point of about 200 - 205°C at 5 mmHg. This product has good solubility in common organic solvents such as toluene, xylene, and ethyl acetate, but it is insoluble in water. The flash point of this compound is relatively high, usually above 170°C, which indicates a relatively low flammability risk under normal conditions.
2 - Ethylhexyl Diphenyl Phosphite is widely used in various industries. In the polymer industry, it serves as an antioxidant and heat - stabilizer. When added to polymers such as polyvinyl chloride (PVC), it can prevent the polymer from degrading due to heat and oxidation during processing and use. This helps to maintain the mechanical properties and appearance of the polymer products, extending their service life.
In the rubber industry, it can be used as a stabilizer for rubber compounds. It protects the rubber from aging caused by oxygen, ozone, and heat, which is crucial for rubber products that are exposed to harsh environmental conditions, such as automotive tires and industrial rubber seals.
It also has applications in the lubricant industry. As an anti - wear and anti - oxidation additive, it can improve the performance of lubricants, reducing friction and wear between moving parts and protecting the lubricant from oxidation and degradation.
When using 2 - Ethylhexyl Diphenyl Phosphite in polymer processing, it should be added during the mixing stage of the polymer formulation. The typical dosage ranges from 0.1% to 2% by weight, depending on the specific polymer type, processing conditions, and the desired level of stabilization. It is recommended to dissolve it in a suitable organic solvent before adding it to the polymer to ensure uniform dispersion.
In the rubber industry, it can be incorporated into the rubber compound during the mixing process on a rubber mixer. Similar to the polymer industry, the dosage should be carefully determined according to the rubber type and the expected performance requirements. Usually, it is added in an amount of 0.5% - 3% by weight.
For lubricant applications, it can be directly added to the lubricant base oil. The addition process should be carried out under mild agitation to ensure good dispersion. The dosage is typically in the range of 0.5% - 5% by weight.
Case 1: PVC Pipe Manufacturing
A PVC pipe manufacturer was facing issues with the discoloration and brittleness of their pipes after long - term outdoor exposure. They added 2 - Ethylhexyl Diphenyl Phosphite to their PVC formulation at a dosage of 1%. After several months of outdoor testing, the pipes showed significantly less discoloration and maintained their flexibility, indicating improved heat and oxidation resistance.
Case 2: Automotive Tire Production
An automotive tire company was looking to enhance the durability of their tires. They incorporated 2 - Ethylhexyl Diphenyl Phosphite into their rubber compound at a dosage of 1.5%. The tires were then subjected to high - speed and long - distance driving tests. The results showed that the tires had less cracking and wear on the sidewalls, demonstrating the effectiveness of the product in preventing rubber aging.
Case 3: Industrial Lubricant
An industrial machinery manufacturer was experiencing frequent lubricant degradation and increased wear of machine parts. They added 2 - Ethylhexyl Diphenyl Phosphite to their lubricant at a dosage of 3%. After continuous operation for a certain period, the lubricant showed much better oxidation stability, and the wear rate of the machine parts was significantly reduced.
