Basic physical properties
Molecular weight: 102.13
Boiling point: 101.6 °C
Density: 0.887 g/cm³ (20 °C)
Refractive index: n²⁰ᴅ ≈ 1.384
Solubility: The solubility of propyl acetate in water is approximately 1.5 g/100 mL (20 °C); it is miscible with ethanol, diethyl ether, acetone, esters, and most resins.
Flash point: 14 °C (closed cup); classified as a flammable liquid (Category 2/3); vapor explosion limits approximately 1.7%–8% v/v
Vapor pressure: Approximately 3.3 kPa at 20 °C; evaporation rate is slower than that of ethyl acetate but faster than that of amyl acetate
Primary Uses
Solvents: Coatings, inks, adhesives, nitrocellulose, and acrylic resins; offers better leveling and slower evaporation than ethyl acetate, making it suitable for medium-drying film systems.
Extractants: Fragrances, essential oils, and the purification of pharmaceutical intermediates.
Organic synthesis: Production of propanol derivatives and specialty esters.
Fragrances: Used in trace amounts for fruity-type fragrances (though less than isoamyl acetate or hexyl acetate).
Safety and Physiology
Toxicity: Low toxicity. Oral LD₅₀ (rat) ≈ 9.5 g/kg; vapors cause mild mucosal irritation, and high concentrations induce dizziness and nausea; liquid contact with eyes causes slight irritation.
Skin: Causes defatting; prolonged contact leads to dryness.
Storage and Transport: Propyl acetate should be stored in a cool, well-ventilated area at a temperature of 30°C or below; use explosion-proof equipment; and store separately from oxidizing agents and strong acids or bases.
FAQ
Q: How safe is it? What should be kept in mind during operation?
A: Classified as a low-toxicity, flammable liquid.
Toxicity: LD₅₀ (oral, rat) approximately 9.4 g/kg; irritating to the eyes and respiratory tract; high concentrations of vapor may cause dizziness and drowsiness.
Protection: Ensure good ventilation during handling; wear safety goggles and chemical-resistant gloves; strictly prohibit open flames and high temperatures.
Q: What are the requirements for storage and transportation?
A: Storage: Store in a tightly sealed container in a cool, dark place; room temperature or refrigerated storage (2–8°C) is recommended. Ensure the container is tightly closed to prevent evaporation.
Transport: Regulated as a flammable liquid (Class 2); UN Number 1276; flammable label required. Not classified as highly toxic or corrosive.
