Octyl Benzyl Phthalate(CAS: 1248-43-7)

Octyl Benzyl Phthalate (CAS: 1248-43-7) is a colorless to light yellow liquid with a slightly aromatic odor. Its molecular weight is approximately 256.33 g/mol. It has a high boiling point of around 325°C and a low melting point of -41°C. Soluble in common organic solvents like ethanol and acetone, but slightly soluble in water. Chemically, it is stable under normal conditions but can be hydrolyzed in strong bases or acids.

Octyl Benzyl Phthalate (CAS: 1248-43-7) is synthesized through the esterification of phthalic anhydride with a mixture of octyl and benzyl alcohols in the presence of an acid catalyst like sulfuric acid. The reaction is carried out at a temperature range of 100-120°C, with an optimal yield of 85-90%. The selectivity towards the desired product is high, and the process is relatively straightforward and cost-effective.

Octyl Benzyl Phthalate (CAS: 1248-43-7) is widely used in the plastic industry as a plasticizer, enhancing the flexibility and plasticity of polyvinyl chloride (PVC). It is also utilized in the cosmetics and fragrance industry as a skin conditioning agent and fixative. Additionally, it finds applications in the coatings and adhesives sector, providing improved adhesion and flexibility.

When handling Octyl Benzyl Phthalate (CAS: 1248-43-7), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be immediately cleaned up using absorbent materials, followed by thorough washing of the spill area. In case of skin or eye contact, immediately rinse with copious amounts of water. For detailed safety information, always refer to the Safety Data Sheet (SDS).
