2-Ethylhexyl diphenyl phosphate(CAS: 1241-94-7)

2-Ethylhexyl diphenyl phosphate is a clear, colorless liquid with a molecular weight of approximately 324.38 g/mol. It has a specific gravity of 1.15 g/cm³ and a flash point of 93°C. The compound is slightly soluble in water but highly soluble in most organic solvents. It is reactive towards bases and can undergo hydrolysis under basic conditions.

2-Ethylhexyl diphenyl phosphate is usually synthesized via the reaction of diphenyl phosphate with 2-ethylhexanol. The reaction is catalyzed by a Lewis acid like aluminum chloride and typically yields high selectivity and good reaction rates. This method provides a yield of about 90%.

2-Ethylhexyl diphenyl phosphate is widely used in the polymer industry as a plasticizer and in the pharmaceutical industry as a stabilizer. It can also be found in sensor applications and as a component in certain semiconductor manufacturing processes. Its use as a flame retardant in some formulations is also a notable application.

When handling 2-Ethylhexyl diphenyl phosphate, it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Spills should be contained and cleaned up using appropriate absorbent materials. Work should be conducted in a well-ventilated area or fume hood. The material safety data sheet (MSDS/SDS) should always be consulted for detailed safety information and emergency procedures.
