Methyl Propionate

Methyl propionate is a colorless, transparent liquid with a sweet, fruity, or rum-like aroma. It is slightly soluble in water; miscible with ethanol, diethyl ether, acetone, and ethyl acetate; and capable of dissolving nitrocellulose as well as certain acrylic and vinyl resins.

Basic physical properties

CAS: 554-12-1
Boiling point: 79.7°C (almost identical to that of ethyl acetate)
Melting point: -87.5°C
Density: 0.915 g/cm³ (20°C)
Refractive index: n²⁰ᴅ ≈ 1.377
Solubility: Methyl propionate is sparingly soluble in water (approximately 6 g/100 mL at 20°C); miscible with ethanol, diethyl ether, acetone, and ethyl acetate; dissolves nitrocellulose and certain acrylic/vinyl resins
Flash point: -2°C (closed cup, CC); some literature cites 6°C (due to open-cup method differences); highly flammable liquid (GHS Category 2)
Vapor pressure: Approx. 11.35 kPa at 25°C; evaporation rate comparable to that of ethyl acetate
Explosion limits: 2.5%–13.0% v/v

Primary Uses

Fast-drying solvent: Nitrocellulose lacquers, coatings, printing inks, and adhesives (evaporation rate similar to ethyl acetate; suitable as a substitute or for blending).
Fragrances/Food flavorings: FEMA GRAS 2752; imparts apple, pineapple, and rum notes; used in soft drinks, confectionery, and baked goods (dosage in the mg/kg range).
Organic synthesis intermediate: Methyl propionate can be used to produce methyl methacrylate (MMA); intermediate for pharmaceuticals and agrochemicals; chromatographic reference standard.
Green solvent research: Derivative of bio-based propionic acid-based processes.

Safety and Physiology

Toxicity: Low toxicity. Oral LD₅₀: ~5000 mg/kg (rat), 3460 mg/kg (mouse); dermal LD₅₀: >5000 mg/kg (rabbit); inhalation LC₅₀: 27,000 mg/m³ (mouse). High vapor concentrations cause dizziness, nausea, and mucous membrane irritation; liquid contact causes moderate eye irritation.
GHS Signal Word: Danger (H225: Highly flammable liquid and vapor; H319: Causes serious eye irritation; H332: Harmful if inhaled).
Storage and Transport: UN 1248, Class 3, PG II; store in a cool, explosion-proof warehouse (≤30°C) separate from oxidizing agents and strong acids/bases; ensure anti-static grounding.

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 3.5 g/kg; it is irritating to the eyes and respiratory tract, and high concentrations of vapor may cause dizziness and nausea. 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 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 (Category 2); flammable labels must be affixed. Not classified as highly toxic or corrosive, but avoid exposure to high temperatures or direct sunlight.
