Diallyl phthalate(CAS: 131-17-9)

Diallyl phthalate is a chemical compound with the CAS number 131-17-9. It is an ester of phthalic acid and allyl alcohol, characterized by its clear, colorless liquid form at room temperature. Diallyl phthalate is known for its high thermal stability and is commonly used as a plasticizer in various polymer applications. It has a molecular formula of C12H14O4 and a molecular weight of approximately 218.24 g/mol.

Diallyl phthalate is primarily used as a plasticizer in the manufacturing of plastics, particularly in polyvinyl chloride (PVC) products. It is also utilized in the production of coatings, adhesives, and sealants due to its excellent flexibility and durability. Additionally, it finds applications in pharmaceuticals, food packaging, and research for its chemical stability and compatibility with various materials.

Diallyl phthalate is generally considered safe when used in accordance with recommended safety guidelines. However, it should be handled with care, as prolonged exposure may cause skin irritation or respiratory issues. Safety data sheets recommend using appropriate personal protective equipment (PPE), such as gloves and goggles, and ensuring proper ventilation. It is classified as a low-toxicity compound but should still be stored and used in compliance with local regulations and safety standards.

Diallyl phthalate should be stored in a cool, dry, and well-ventilated area away from direct sunlight. It is best kept in a sealed container made of glass or high-density polyethylene (HDPE) to prevent contamination and evaporation. Storage conditions should maintain a temperature between 0°C and 25°C and a relative humidity level below 60%. Proper labeling and storage in a chemical storage cabinet are recommended to ensure safety and stability.
