Diethyl phthalate (DEP), with CAS No. 84-66-2, a molecular formula of C₁₂H₁₄O₄, and a molecular weight of 222.24, is a commonly used plasticizer, solvent, and fragrance fixative, with properties intermediate between those of DMP and DBP.
- Appearance: Colorless, transparent oily liquid with a slight aromatic odor.
- Key parameters: melting point approximately −4°C, boiling point approximately 295°C, density approximately 1.12 g/cm³ at 20°C, refractive index n₂₀ᴰ 1.501, flash point approximately 155°C.
- Solubility: Slightly soluble in water (approximately 1.08 g/L at 25°C); readily soluble in organic solvents such as ethanol, diethyl ether, acetone, and benzene.
- Properties: Compatible with a wide range of resins; excellent film-forming, adhesion, and water-resistant properties; lower volatility than DMP; often used in combination with DMP to enhance low-temperature flexibility and water resistance.
Uses
1. Plasticizers: Compatible with cellulose acetate, cellulose nitrate, ethyl cellulose, polystyrene, and other materials; used in films, varnishes, inks, adhesives, and non-toxic food-packaging adhesives, among others.
2. Solvents and Intermediates: solvents for coatings and inks, pharmaceutical extraction agents, rodenticides (such as diphacinone) intermediates; gas chromatography stationary phases (up to 95°C), used for the separation of aromatics, unsaturated compounds, and other substances.
3. Daily chemicals and fragrances: Used as a fragrance fixative in cosmetics and as a plasticizer in nail polish; serves as a solvent in perfumes and hair sprays to prolong scent longevity.
4. Other: flotation frothers for mining, alcohol denaturants, and ingredients for aerosol insecticides.
