Propyl acetate

Propyl acetate is an organic chemical compound with the molecular formula C5H10O2 and CAS number 109-60-4. It belongs to the ester family, formed by the reaction between propanol and acetic acid. With a molecular weight of 102.13 g/mol, this colorless liquid is classified as a flammable substance and mild irritant. It is widely used in industrial applications as a solvent and chemical intermediate due to its favorable properties and relatively low toxicity profile.

Propyl acetate is a colorless liquid with a characteristic fruity, sweet odor reminiscent of pears. It has good solubility in organic solvents but limited solubility in water. The compound exhibits moderate volatility at room temperature and has a relatively low boiling point. Its ester structure gives it excellent solvating properties for various organic compounds, making it particularly useful in coating and adhesive formulations where controlled evaporation rates are desired.

Propyl acetate is primarily used as a solvent in the paint, coating, and adhesive industries due to its excellent dissolving properties and moderate evaporation rate. It serves as a key component in lacquers, printing inks, and nail polish formulations. Additionally, it finds applications in the production of artificial flavors and fragrances, where its fruity aroma is valued. The chemical industry also uses it as an intermediate in various synthesis processes and as a cleaning agent in specialized applications.

Propyl acetate requires careful handling due to its flammable nature (Flam. Liq. 2) and irritant properties. Essential personal protective equipment includes safety goggles to prevent eye irritation, chemical-resistant gloves, and adequate ventilation to avoid inhalation. Work areas must be free from ignition sources, sparks, and open flames. Ground all equipment to prevent static electricity buildup. Use explosion-proof electrical equipment in areas where vapors may accumulate and ensure emergency eyewash stations are readily accessible.

Propyl acetate must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Class 2 flammability. Storage containers should be tightly sealed and made of compatible materials to prevent contamination. Keep away from strong oxidizing agents and acids to avoid dangerous reactions. Storage areas should have appropriate fire suppression systems and be designed to contain potential spills. Maintain storage temperatures below 25°C when possible to minimize vapor formation.

Propyl acetate contact requires immediate action to prevent irritation. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. If breathing difficulties occur, provide oxygen and seek medical help. For ingestion, do not induce vomiting and seek immediate medical attention.

Propyl acetate disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance should never be disposed of down drains or into the environment. Preferred disposal methods include incineration at licensed hazardous waste facilities or recovery through distillation when economically viable. Contaminated containers must also be treated as hazardous waste. Always consult with certified waste management companies and follow waste classification codes according to the European Waste Catalogue for proper disposal documentation.

Propyl acetate is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport protocols. Vehicles must carry appropriate hazard placards and transport documentation. Packages must meet UN specification standards for Class 3 substances and be properly labeled with GHS02 and GHS07 pictograms. Drivers require ADR certification for dangerous goods transport. Emergency response information must be available during transport, and routes should avoid tunnels with restrictions for Class 3 materials where applicable.

Propyl acetate is subject to European REACH regulation and must comply with CLP classification requirements. It is classified as Flam. Liq. 2, STOT SE 3, and Eye Irrit. 2, requiring appropriate labeling with danger signal word and GHS pictograms. The substance is not currently listed as an SVHC (Substance of Very High Concern). Workplace exposure limits may apply depending on national regulations. Industrial users must ensure proper risk assessments and safety data sheet distribution according to REACH and CLP requirements.
