Ethyl Acetate

Ethyl acetate, commonly known as acetic ether, is a colorless, transparent liquid with a fresh, fruity aroma (resembling pears or glue); it is one of the most widely used low-molecular-weight fatty acid esters in industry. It is a highly flammable liquid whose vapors can form explosive mixtures with air; it is stable to light but decomposes readily when exposed to strong acids, strong bases, or heat, and it does not easily undergo spontaneous polymerization.

Basic physical properties

Molecular weight: 88.11
Boiling point: 77.1 °C
Density: 0.902 g/cm³ (20 °C)
Refractive index: n²⁰ᴅ ≈ 1.372
Solubility: The solubility of ethyl acetate in water is approximately 8.3 g/100 mL (20 °C); it is miscible with ethanol, diethyl ether, acetone, benzene, and chloroform; and it dissolves nitrocellulose, resins, and oils.
Flash point: -4 °C (closed cup); highly flammable liquid (Category 2); vapors can form explosive mixtures with air (explosive limits approx. 2.2%–11% v/v)
Vapor pressure: Approx. 9.7 kPa at 20 °C; evaporation rate is between that of methyl acetate and amyl acetate

Primary Uses

Solvents: Coatings, inks, adhesives, pharmaceutical crystallization, and extraction (e.g., decaffeination, antibiotic purification)
Organic synthesis: Production of ethyl acetoacetate, dyes, fragrances, and pharmaceutical intermediates
Food/Flavorings: Ethyl acetate is permitted for use as a food flavoring (fruity aroma); however, industrial-grade material must not be used directly in food.
Electronics cleaning: Substitute for halogenated hydrocarbons in certain precision cleaning applications (note: low flash point requires explosion-proof measures)

Safety and Physiology

Toxicity: Low toxicity. Oral LD₅₀ (rat) ≈ 5.6 g/kg; high-concentration vapors cause mucous membrane irritation, dizziness, and nausea; prolonged inhalation leads to mild anesthesia; liquid contact causes eye irritation.
Skin: Degreasing effect; repeated contact causes dryness.
Storage and Transport: Fire safety is critical-store at ≤ 30°C; use explosion-proof electrical equipment; store separately from oxidizing agents, acids, and alkalis; ensure anti-static grounding for drummed containers.

FAQ

Q: How safe is it? What should be kept in mind during operation?

A: A liquid of low toxicity and high flammability.

Toxicity: LD₅₀ (rat, oral) is approximately 5.6 g/kg; it is highly irritating to the eyes and respiratory tract, and high concentrations of vapor can cause dizziness, drowsiness, and a narcotic effect.

Protection: Ensure strong 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 sealed container in a cool, dark place; room temperature or refrigerated storage (2–8°C) is recommended. Containers must be tightly closed to prevent evaporation.

Transport: Regulated as a flammable liquid (Class 2); UN Number 1173; flammable label required. Not classified as highly toxic or corrosive.
