Ethyl butanoate

Ethyl butanoate is an organic ester compound with the molecular formula C6H12O2 and CAS number 105-54-4. It has a molecular weight of 116.16 g/mol and is formed by the esterification of butanoic acid with ethanol. This colorless liquid compound is known for its pleasant, fruity aroma reminiscent of pineapple or apple. Ethyl butanoate occurs naturally in various fruits and is widely used in the food, fragrance, and chemical industries as a flavoring agent and solvent.

Ethyl butanoate is a colorless liquid at room temperature with a characteristic sweet, fruity odor similar to pineapple or banana. It has a boiling point of approximately 121°C and a density of about 0.879 g/cm³. The compound is slightly soluble in water but readily miscible with alcohol and most organic solvents. It exhibits typical ester properties including susceptibility to hydrolysis under acidic or basic conditions and has a relatively low viscosity.

Ethyl butanoate is primarily used as a flavoring agent in the food and beverage industry, providing fruity notes in products like candies, baked goods, and beverages. It serves as a fragrance component in perfumes, cosmetics, and household products. In industrial applications, it functions as a solvent for coatings, inks, and adhesives. The compound is also utilized in chemical synthesis as an intermediate for producing other organic compounds and in pharmaceutical formulations.

Ethyl butanoate should be handled in well-ventilated areas to prevent vapor accumulation. Wear appropriate personal protective equipment including safety goggles, gloves resistant to organic solvents, and protective clothing. Avoid direct skin and eye contact, and prevent inhalation of vapors. Use non-sparking tools and equipment since it is classified as a flammable liquid (ADR Class 3). Keep away from ignition sources, heat, and open flames during handling and processing operations.

Ethyl butanoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Maintain storage temperatures below 25°C to minimize evaporation and degradation. Keep containers in upright position and away from incompatible materials such as strong oxidizing agents and strong acids or bases. Ensure proper grounding and bonding during transfer operations to prevent static electricity buildup due to its flammable nature.

Ethyl butanoate contact requires immediate action depending on exposure route. For skin contact, remove contaminated clothing and wash 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 and ensure they rest in a comfortable position. If swallowed, do not induce vomiting and seek immediate medical advice.

Ethyl butanoate disposal must comply with local and national waste management regulations as it is classified as hazardous waste due to its flammable properties. Contact licensed waste disposal companies specialized in organic solvent treatment. Small quantities may be disposed of through approved incineration facilities with appropriate emission controls. Never dispose of in sewers, water courses, or regular waste streams. Maintain proper documentation of waste disposal for regulatory compliance and environmental protection.

Ethyl butanoate is classified under ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. It must be packed in UN-approved containers and properly labeled with appropriate hazard markings. Vehicles must carry appropriate safety equipment and drivers require ADR certification. During transport, ensure containers are properly secured, sealed, and protected from temperature extremes and mechanical damage. Follow specific routing restrictions for hazardous materials where applicable.

Ethyl butanoate is subject to REACH regulation in Europe and must be registered for commercial use above certain tonnage thresholds. It is not classified as a Substance of Very High Concern (SVHC) and has no specific restrictions under REACH Annex XVII. The compound must comply with CLP regulation for classification, labeling, and packaging. Food-grade applications require compliance with food contact regulations, and workplace exposure limits may apply depending on national legislation.
