It is a phosphite ester, which is known for its chemical stability and reactivity properties. The physical state of this product is usually a liquid. Its molecular formula is C₂₂H₃₇O₃P, and the molecular weight is approximately 384.5 g/mol. The purity of the product is maintained at a high level to ensure its effectiveness in various applications. It has a relatively low viscosity, which makes it easy to handle during processing.

Usage of the Product

bis(2-ethylhexyl) phenyl phosphite has a wide range of applications. In the polymer industry, it is used as an antioxidant and stabilizer. It can prevent the polymer from degradation caused by heat, oxygen, and light during processing and use. This helps to extend the service life of polymer products such as plastics, rubber, and fibers. In the lubricant industry, it can improve the oxidation resistance and anti - wear performance of lubricants. It forms a protective film on the metal surface, reducing friction and wear, and thus enhancing the efficiency and durability of mechanical equipment. Additionally, it can be used as an intermediate in the synthesis of other chemicals, providing a starting point for the production of more complex compounds.

How to Use the Product

When using bis(2-ethylhexyl) phenyl phosphite, it is important to follow proper safety and handling procedures. First, make sure to store the product in a cool, dry place away from direct sunlight and heat sources. When adding it to a reaction system or a mixture, it should be added gradually under stirring conditions to ensure uniform dispersion. For polymer processing, it can be added during the compounding stage. The recommended dosage usually depends on the specific polymer and the required level of stabilization, typically ranging from 0.1% to 1% by weight. In the lubricant industry, it can be directly blended with base oils, and the dosage is also determined according to the performance requirements of the lubricant, generally between 0.5% and 2%.

Detailed Use Cases

Case 1: In a plastic manufacturing plant, a company was producing polypropylene (PP) products. They were facing issues with the yellowing and brittleness of PP products during long - term use. After adding bis(2-ethylhexyl) phenyl phosphite at a dosage of 0.5% by weight during the extrusion process, the oxidation resistance of the PP products was significantly improved. The yellowing phenomenon was reduced, and the mechanical properties such as tensile strength and elongation at break were maintained at a high level even after long - term exposure to heat and light.

Case 2: A lubricant manufacturer was developing a high - performance engine oil. By adding this product at a dosage of 1.5% to the base oil, the oxidation stability of the engine oil was enhanced. The oil showed less viscosity increase and sludge formation during high - temperature operation, which improved the overall performance and service life of the engine. The engine also ran more smoothly, and fuel efficiency was slightly improved.
