2-ethylbutyl acetate

2-ethylbutyl acetate is an organic chemical compound with the molecular formula C8H16O2 and CAS number 10031-87-5. This ester has a molecular weight of 144.21 g/mol and belongs to the acetate family. It is formed by the esterification of 2-ethylbutanol with acetic acid, resulting in a branched-chain acetate ester with distinctive chemical properties used in various industrial applications.

2-ethylbutyl acetate is a colorless to pale yellow liquid at room temperature with a characteristic fruity, sweet odor typical of acetate esters. It has low solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound exhibits moderate volatility and has a density lower than water, making it suitable for solvent applications.

2-ethylbutyl acetate is primarily used as a solvent in the coatings, paints, and varnish industry due to its excellent solvency properties and pleasant odor profile. It serves as a coalescent in latex paints, helping film formation during drying. Additionally, it finds applications in adhesives, printing inks, and as a flavoring agent in the food industry, where its fruity aroma is valued.

2-ethylbutyl acetate should be handled with standard chemical safety precautions including wearing appropriate personal protective equipment such as safety goggles, chemical-resistant gloves, and adequate ventilation. Work in well-ventilated areas to prevent vapor accumulation. Avoid contact with skin and eyes, and prevent inhalation of vapors. Use non-sparking tools and ensure proper grounding when transferring the material to prevent static electricity buildup.

2-ethylbutyl 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 in original packaging or compatible containers made of materials resistant to acetate esters. Maintain storage temperatures below 25°C when possible and ensure adequate fire prevention measures are in place due to its flammable nature.

In case of skin contact with 2-ethylbutyl acetate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. If swallowed, do not induce vomiting and seek medical attention promptly.

2-ethylbutyl acetate waste must be disposed of in accordance with local, national, and European waste regulations. The material should be collected in appropriate containers and handed over to licensed waste disposal companies for proper treatment or incineration at authorized facilities. Do not discharge into drains, waterways, or soil. Consider recycling options where available and economically viable for large quantities.

2-ethylbutyl acetate is classified under ADR transport regulations as Class 3 (flammable liquids), Packing Group III. It requires appropriate UN-specification packaging and proper labeling during transport. Vehicles must carry appropriate fire extinguishing equipment and drivers need ADR certification. The material should be transported in accordance with dangerous goods regulations and kept away from heat sources and incompatible materials during transit.

2-ethylbutyl acetate is subject to standard European chemical regulations including REACH registration requirements and CLP classification and labeling regulation. It is not listed as a Substance of Very High Concern (SVHC) and does not require authorization under REACH Annex XIV. However, users must comply with workplace safety regulations, environmental protection laws, and proper classification for transport as a flammable liquid.
