Характеристики

Ключевые свойства и преимущества

Low viscosity and excellent wetting properties allow for easy blending and uniform distribution within complex polymer matrices or liquid formulations.
Exceptional chemical stability ensures that the compound remains non-reactive under standard storage conditions, maintaining product integrity over extended periods.
High boiling point and low vapor pressure compared to other small-molecule esters make it an ideal candidate for heat-intensive processing.
Superior compatibility with cellulose acetate and nitrocellulose provides critical flexibility and durability to various specialty plastic and coating applications.
Acting as a dual-purpose additive, it serves simultaneously as an effective solvent and a reliable plasticizer in diverse chemical industries.

Спецификации

Технические особенности

Molecular Weight: Approximately 222.24 g/mol, supporting its classification as a medium-sized phthalate ester with predictable thermodynamic behavior.
Density and Refractive Index: Exhibits a specific gravity of roughly 1.120 at 25°C and a refractive index near 1.502.
Boiling Point: Ranges between 295°C to 298°C at atmospheric pressure, demonstrating its suitability for high-temperature industrial manufacturing environments.
Solubility Parameters: Miscible in ethanol, diethyl ether, and benzene, while maintaining a very low aqueous solubility of approximately 1,000 mg/L.
Flash Point: Typically measured at 156°C (312.8°F) using closed-cup methods, indicating moderate fire risk during handling and storage operations.

Практическое применение в отраслях

Области применения

Fragrance Fixative: Used extensively in perfumes and colognes to retard evaporation and prolong the longevity of volatile aromatic compounds.
Plasticizer Production: Employed specifically in the manufacturing of cellulose acetate films, tools, and automotive parts to enhance mechanical flexibility.
Alcohol Denaturant: Added to ethanol intended for cosmetic or industrial use to make it unpalatable, preventing diversion for human consumption.
Coating Additive: Integrated into lacquers, varnishes, and printing inks to improve adhesion, film formation, and overall resistance to cracking.
Personal Care: Functions as a solvent and stabilizer in hairsprays, nail polishes, and deodorants, ensuring product consistency and performance.
