Propyl acetate

Propyl acetate is an organic chemical compound with the molecular formula C5H10O2 and CAS number 109-60-4. This ester has a molecular weight of 102.13 g/mol and is formed by the reaction between propanol and acetic acid. It belongs to the acetate ester family and is commonly used as a solvent in various industrial applications. The compound is classified as a flammable liquid with moderate hazard properties under the GHS classification system.

Propyl acetate is a colorless liquid with a characteristic fruity, sweet odor reminiscent of pears or apples. It has good solubility in organic solvents but limited solubility in water. The compound exhibits typical ester properties with moderate volatility and boiling point. Its density is lower than water, and it forms a separate layer when mixed with aqueous solutions. These physical properties make it an effective solvent for various organic compounds and resins.

Propyl acetate is primarily used as a solvent in the paint, coating, and printing ink industries due to its excellent dissolving properties for resins, cellulose derivatives, and other organic materials. It serves as a solvent in adhesives, lacquers, and specialty coatings. The compound is also utilized in the production of artificial flavors and fragrances, particularly for fruit-like scents. Additionally, it finds applications in cleaning formulations and as a processing aid in various chemical manufacturing processes.

Propyl acetate requires careful handling due to its flammable nature and potential health effects. Wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing to prevent eye and skin contact. Ensure adequate ventilation to avoid inhalation of vapors, which may cause respiratory tract irritation. Keep away from ignition sources, heat, and open flames. Use explosion-proof equipment when necessary and maintain proper grounding to prevent static electricity buildup during handling operations.

Propyl acetate should be stored in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Use appropriate containers made of compatible materials and ensure they are tightly sealed to prevent vapor release. Store separately from oxidizing agents, strong acids, and bases to avoid incompatible reactions. Maintain storage temperatures below 25°C when possible and implement proper fire prevention measures including appropriate fire suppression systems in storage areas.

In case of skin contact with propyl acetate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor for respiratory symptoms. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist or worsen.

Propyl acetate must be disposed of in accordance with local, national, and international waste regulations as a hazardous chemical waste. Do not pour down drains or dispose of in regular waste streams. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities may be recovered through distillation for reuse where appropriate. Contaminated containers should also be disposed of as hazardous waste unless properly cleaned and decontaminated according to regulatory requirements.

Propyl acetate is classified as ADR Class 3 (flammable liquid), Packing Group II, requiring specific transport regulations. Use appropriate UN-approved packaging and containers designed for flammable liquids. Transport vehicles must comply with ADR requirements including proper placarding, documentation, and safety equipment. Drivers must hold valid ADR certification for Class 3 substances. Ensure proper loading, segregation from incompatible materials, and adherence to quantity limitations for different transport categories during shipment.

Propyl acetate is regulated under REACH regulation in the European Union and requires registration for commercial use above specified tonnage thresholds. It falls under CLP regulation for classification, labeling, and packaging requirements with assigned hazard classes including Flam. Liq. 2, STOT SE 3, and Eye Irrit. 2. The substance is not currently listed as an SVHC (Substance of Very High Concern). Workplace exposure limits may apply in different jurisdictions, requiring compliance with occupational safety regulations.
