Butan-2-yl acetate

Butan-2-yl acetate is an organic chemical compound with the molecular formula C6H12O2 and CAS number 105-46-4. It belongs to the ester family, formed by the reaction between acetic acid and butan-2-ol (sec-butanol). With a molecular weight of 116.16 g/mol, this compound is commonly used as a solvent in various industrial applications due to its favorable volatility and dissolving properties.

Butan-2-yl acetate is a colorless liquid at room temperature with a characteristic fruity, ester-like odor. It has moderate volatility and is partially soluble in water while being miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound exhibits typical ester properties with good stability under normal conditions and a relatively low boiling point, making it suitable for various solvent applications.

Butan-2-yl acetate is primarily used as a solvent in the paint and coatings industry, providing excellent flow properties and film formation. It serves as a thinner for lacquers, enamels, and automotive finishes. Additionally, it finds applications in the production of printing inks, adhesives, and cleaning formulations. Its favorable evaporation rate makes it valuable in applications requiring controlled drying times and smooth surface finishes.

Butan-2-yl acetate should be handled in well-ventilated areas or under local exhaust ventilation to prevent vapor accumulation. Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Avoid contact with skin and eyes, and prevent inhalation of vapors. Keep away from ignition sources, hot surfaces, and open flames as the compound is flammable. Use non-sparking tools and ensure proper grounding of equipment.

Butan-2-yl acetate should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed when not in use and store in original containers or approved alternatives. Maintain storage temperature below 25°C and avoid direct sunlight. Store away from strong oxidizing agents, acids, and bases. Ensure storage areas are equipped with appropriate fire suppression systems and spill containment measures.

In case of skin contact with butan-2-yl acetate, immediately wash the affected area with soap and plenty of water for at least 15 minutes. For eye contact, rinse thoroughly with clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and keep them comfortable for breathing. In case of ingestion, do not induce vomiting and seek immediate medical attention. Remove contaminated clothing and wash before reuse.

Butan-2-yl acetate must be disposed of according to local, regional, and national waste regulations as a flammable liquid waste. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into drains, waterways, or soil. Small quantities may be suitable for solvent recovery or incineration at authorized facilities. Always consult safety data sheets and local environmental authorities for specific disposal requirements in your region.

Butan-2-yl acetate is classified as ADR Class 3 (flammable liquids), Packing Group II for transportation purposes. It must be transported in approved containers and vehicles equipped for flammable liquid transport. Proper shipping documentation, hazard labels, and placards are required. Drivers must hold appropriate dangerous goods training certificates. Avoid transport during extreme temperatures and ensure vehicles are equipped with appropriate fire extinguishing equipment and spill response materials.

Butan-2-yl acetate is subject to REACH regulation requiring registration for manufacture or import above certain tonnages in the EU. It must comply with CLP regulation for classification, labeling, and packaging requirements. The substance is not classified as SVHC (Substance of Very High Concern) under REACH. Industrial users should maintain safety data sheets and implement appropriate risk management measures. Always check current regulatory status as requirements may evolve over time.
