Butyl acetate

Butyl acetate is an organic chemical compound with the molecular formula C6H12O2 and CAS number 123-86-4. It belongs to the ester family, formed by the reaction of butanol and acetic acid. With a molecular weight of 116.16 g/mol, this colorless liquid is widely used as a solvent in various industrial applications due to its excellent dissolving properties and relatively low toxicity compared to other organic solvents.

Butyl acetate is a colorless liquid with a characteristic fruity, banana-like odor. It has a boiling point of approximately 126°C and a density of about 0.88 g/cm³ at 20°C. The compound is partially soluble in water (approximately 1% at 20°C) but miscible with most organic solvents including alcohols, ethers, and hydrocarbons. It exhibits low viscosity and good volatility, making it an effective solvent for various applications.

Butyl acetate is primarily used as a solvent in paints, lacquers, and coatings due to its excellent dissolving power and moderate evaporation rate. It serves as a key component in nail polish, adhesives, and printing inks. The chemical industry utilizes it in the production of artificial leather, plastics, and as an extraction solvent. Additionally, it finds applications in the food industry as a flavoring agent and in pharmaceuticals as a processing solvent.

Butyl acetate requires careful handling as it is classified as a flammable liquid (Flam. Liq. 3) and may cause specific target organ toxicity (STOT SE 3). Use appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and ensure adequate ventilation. Avoid sources of ignition, heat, and sparks. Work in well-ventilated areas or use local exhaust ventilation to prevent vapor accumulation. The GHS pictograms GHS02 and GHS07 indicate fire and health hazards respectively.

Butyl acetate should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed and store below 25°C to minimize vapor formation. Use appropriate containers made of compatible materials and ensure proper grounding to prevent static electricity buildup. Store separately from strong oxidizing agents, acids, and bases. Implement appropriate fire prevention measures and maintain adequate spacing between storage areas and ignition sources.

Butyl acetate exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for detailed emergency procedures.

Butyl acetate waste must be disposed of in accordance with local, national, and international environmental regulations. It is classified as hazardous waste and cannot be disposed of with regular waste streams. Contact licensed waste disposal companies for proper treatment, which may include incineration at approved facilities or solvent recovery processes. Never discharge into sewers, waterways, or soil. Small quantities may be allowed for evaporation in well-ventilated areas following local regulations and safety procedures.

Butyl acetate is classified under ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) as Class 3 (flammable liquids), Packing Group III. This classification indicates it has a relatively low degree of danger compared to other flammable substances. Transportation requires appropriate packaging, labeling with hazard diamonds, and compliance with quantity limitations. Vehicles must carry proper documentation, emergency equipment, and drivers need ADR training certification for commercial transport.

Butyl acetate is regulated under various European frameworks including REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational exposure limits, workplace safety regulations, and environmental discharge standards. The substance requires proper classification, labeling with GHS pictograms, and safety data sheet distribution throughout the supply chain.
