FAQ

What are the physical and chemical properties of Didecyl phthalate (CAS: 84-77-5)?

Didecyl phthalate (CAS: 84-77-5) is a colorless to light yellow liquid with a molecular weight of approximately 344.46 g/mol. It has a high boiling point (290-295°C) and low solubility in water (0.5 g/100 mL at 20°C). It is slightly soluble in ethanol and readily soluble in organic solvents such as toluene. It exhibits low reactivity under normal conditions but can degrade under prolonged exposure to heat or light.

How is didecyl phthalate (CAS: 84-77-5) typically synthesized?

Didecyl phthalate (CAS: 84-77-5) is typically synthesized through the esterification of phthalic anhydride with decyl alcohol in the presence of a strong acid catalyst, such as concentrated sulfuric acid. The reaction yields a phthalate ester with a high selectivity and good yield. The process involves heating the reactants to around 80°C for several hours under stirring conditions.

What industries use didecyl phthalate (CAS: 84-77-5)?

Didecyl phthalate (CAS: 84-77-5) is widely used in the polymers industry for plasticizers, in the pharmaceutical industry as a stabilizer, and in the food industry as a flavor enhancer. It is also utilized in the manufacturing of coatings, inks, and adhesives. Additionally, it has applications in the production of sensors and semiconductors due to its stability and chemical inertness.

What precautions should be taken when handling didecyl phthalate (CAS: 84-77-5)?

When handling didecyl phthalate (CAS: 84-77-5), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, protective clothing, and safety goggles. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation of vapors. In case of a spill, contain it with absorbent materials and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
