Di-2-octanyl phthalate(CAS: 131-15-7)

Di-2-octanyl phthalate (CAS: 131-15-7) is a colorless or slightly yellow liquid at room temperature. It has a molecular weight of approximately 394.47 g/mol and a melting point of about -17°C. This compound is slightly soluble in water but highly soluble in organic solvents. It is reactive towards bases and exhibits some ester hydrolysis. The compound is used in various applications, including plasticizers and coatings.

Di-2-octanyl phthalate (CAS: 131-15-7) is typically synthesized by esterification of phthalic anhydride with 2-ethylhexanol. The reaction is catalyzed by a strong acid like sulfuric acid or p-toluenesulfonic acid. The process involves heating under reflux for several hours, followed by neutralization and purification steps. The yield is usually around 85-90%.

Di-2-octanyl phthalate (CAS: 131-15-7) is predominantly used in the plastic industry as a plasticizer for polyvinyl chloride (PVC) and other polymers. It is also employed in the formulation of coatings, adhesives, and sealants. Additionally, it has applications in the pharmaceutical industry for the production of soft gels and in the manufacturing of some types of sensors and semiconductors.

When handling Di-2-octanyl phthalate (CAS: 131-15-7), appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be cleaned up immediately with appropriate absorbent materials. Should an exposure occur, contact a healthcare professional. Always refer to the Safety Data Sheet (SDS) for specific handling instructions and emergency procedures.
