Butyl acetate

Butyl acetate is an organic chemical compound with the molecular formula C6H12O2 and CAS number 123-86-4. This ester has a molecular weight of 116.16 g/mol and is formed by the combination of butanol and acetic acid. It is classified as a flammable liquid (Category 3) and causes specific target organ toxicity following single exposure (Category 3). The substance presents moderate hazards and requires appropriate handling precautions in industrial applications.

Butyl acetate is a colorless liquid with a characteristic fruity, banana-like odor at room temperature. It has limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a relatively low viscosity and moderate volatility. Its ester functional group makes it an effective solvent for various organic compounds, resins, and polymers, which contributes to its widespread industrial utility.

Butyl acetate is primarily used as a solvent in the paint, coating, and lacquer industries due to its excellent solvency properties and moderate evaporation rate. It serves as a key component in nail polish formulations, printing inks, and adhesives. The compound is also utilized in the production of leather finishes, wood stains, and as an extraction solvent in various chemical processes. Its fruity odor makes it valuable in flavoring applications within the food industry.

Butyl acetate requires careful handling due to its flammable nature and potential health effects. Personal protective equipment should include safety goggles, chemical-resistant gloves, and appropriate respiratory protection in poorly ventilated areas. Work areas must be well-ventilated and free from ignition sources. Ground all equipment to prevent static electricity buildup. Avoid prolonged skin contact and inhalation of vapors, as the substance can cause specific target organ toxicity and irritation.

Butyl acetate should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly sealed and store below 25°C to minimize vapor formation. The storage area should be equipped with appropriate fire suppression systems and spill containment measures. Avoid storage near strong oxidizing agents and incompatible materials. Ensure proper grounding of storage tanks and use explosion-proof electrical equipment in storage areas.

In case of skin contact with butyl acetate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention if respiratory irritation occurs. For eye contact, flush eyes with clean water for at least 15 minutes and remove contact lenses if present. If ingested, do not induce vomiting and seek immediate medical attention.

Butyl acetate waste must be disposed of in accordance with local, national, and international waste regulations. The substance should be collected in appropriate containers and delivered to licensed waste treatment facilities for incineration or recovery. Do not discharge into drains, waterways, or soil. Small quantities can be evaporated in a fume hood under controlled conditions. Always consult with waste management specialists and follow applicable environmental regulations for proper disposal procedures.

Butyl acetate is classified under ADR Class 3 (Flammable Liquids), Packing Group III for transportation purposes. It must be packaged in UN-approved containers and labeled with appropriate hazard placards including flammable liquid warnings. Transport vehicles should be equipped with fire extinguishers and emergency response equipment. Drivers must carry proper documentation and be trained in hazardous materials handling. Ensure adequate ventilation during transport and avoid exposure to heat sources.

Butyl acetate is regulated under various European legislation including REACH regulation, requiring registration for manufacture or import above one tonne per year. It falls under CLP regulation with mandatory hazard classification as Flammable Liquid Category 3 and STOT SE Category 3. The substance is not identified as a Substance of Very High Concern (SVHC). Industrial users must comply with workplace exposure limits and safety data sheet requirements for proper risk management and worker protection.
