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 of acetic acid with butan-2-ol (sec-butanol). With a molecular weight of 116.16 g/mol, this colorless liquid exhibits typical ester characteristics and is commonly used as a solvent in various industrial applications.

Butan-2-yl acetate is a colorless liquid with a characteristic fruity, sweet odor typical of acetate esters. It has moderate solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a molecular weight of 116.16 g/mol and exhibits typical ester properties such as moderate volatility and flammability.

Butan-2-yl acetate is primarily used as a solvent in the coatings, paints, and varnish industry due to its excellent dissolving properties and moderate evaporation rate. It serves as a solvent for cellulose derivatives, resins, and various polymers. Additionally, it finds applications in the production of lacquers, printing inks, and as a component in industrial cleaning formulations where its solvency power is beneficial.

Butan-2-yl acetate should be handled in well-ventilated areas or under local exhaust ventilation to prevent vapor accumulation. Use appropriate personal protective equipment including chemical-resistant gloves, safety glasses, and protective clothing. Avoid sources of ignition as the substance is flammable. Ensure electrical equipment is explosion-proof when working with larger quantities. Keep containers tightly closed when not in use.

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 sealed to prevent evaporation and contamination. Store away from strong oxidizing agents and acids to prevent incompatible reactions. Maintain storage temperature below 25°C when possible and ensure proper fire prevention measures are in place due to its flammable nature.

In case of skin contact with butan-2-yl acetate, immediately wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention if irritation persists. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical attention promptly.

Butan-2-yl acetate waste must be disposed of according to local and national environmental regulations as hazardous waste. Do not pour down drains or into the environment. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may be suitable for solvent recovery processes. Always consult local environmental authorities for specific disposal requirements and ensure proper waste classification documentation.

Butan-2-yl acetate is classified under ADR as Class 3 (flammable liquids), Packing Group II, indicating moderate danger. It must be transported in approved packaging suitable for flammable liquids and properly labeled with appropriate hazard markings. Vehicles must comply with ADR regulations for Class 3 substances, including proper ventilation, fire prevention measures, and emergency equipment. Professional transport companies with ADR certification should handle shipments.

Butan-2-yl acetate is subject to REACH regulation and must be registered for use in the European Union. It is not classified as a Substance of Very High Concern (SVHC) and currently has no specific CLP classification for health or environmental hazards. However, its flammable nature requires compliance with workplace safety regulations and proper handling procedures according to national occupational safety standards.
