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 reaction between ethanol and butanoic acid. This colorless liquid is characterized by its pleasant, fruity aroma reminiscent of pineapple or apple, making it valuable in various industrial applications where fragrance is important.

Ethyl butanoate is a colorless liquid at room temperature with a characteristic sweet, fruity odor similar to pineapple. It has limited solubility in water but is miscible with most organic solvents including alcohols and ethers. The compound has a relatively low boiling point and moderate volatility. As an ester, it can undergo hydrolysis in the presence of acids or bases, breaking down into its constituent alcohol and carboxylic acid components.

Ethyl butanoate is primarily used as a flavoring agent in the food and beverage industry due to its pleasant fruity aroma and taste. It serves as an important ingredient in artificial fruit flavorings, particularly for pineapple and apple profiles. Additionally, it finds applications in the fragrance industry for cosmetics and personal care products, and as a solvent in various chemical processes and formulations where a pleasant-smelling, volatile organic compound is required.

Ethyl butanoate should be handled in well-ventilated areas to prevent vapor accumulation, as it is classified as a flammable liquid (ADR Class 3). Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Avoid sources of ignition, heat, and sparks during handling. Ensure proper grounding and bonding when transferring the material. Work with adequate ventilation or use local exhaust ventilation to control vapor exposure levels.

Ethyl butanoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its flammable nature. Keep containers in a temperature-controlled environment to prevent excessive vapor pressure buildup. Store away from strong oxidizing agents, acids, and bases to prevent unwanted reactions. Ensure storage areas comply with local fire safety regulations for flammable liquids and maintain proper inventory rotation practices.

In case of skin contact with ethyl butanoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15-20 minutes and seek medical attention if irritation persists. For inhalation exposure, move the person to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention while providing the safety data sheet to medical personnel.

Ethyl butanoate must be disposed of according to local, national, and European waste regulations as a flammable liquid waste. Contact licensed waste disposal companies specializing in organic solvents and esters for proper collection and treatment. Do not pour down drains, sewers, or onto the ground as this may contaminate water sources. Small quantities may be suitable for solvent recovery processes, while larger amounts typically require incineration at authorized hazardous waste facilities with appropriate emission controls.

Ethyl butanoate is classified under ADR as Class 3 (flammable liquids), Packing Group III for transportation purposes. It must be packaged in UN-approved containers and labeled with appropriate hazard markings and transport documentation. Vehicles transporting this material must comply with ADR regulations for flammable liquids, including proper placarding, equipment requirements, and driver training. Ensure proper securing of packages and avoid transport during extreme temperature conditions to prevent container pressure buildup.

Ethyl butanoate is subject to standard European chemical regulations including REACH registration requirements and CLP classification obligations. It is not identified as a Substance of Very High Concern (SVHC) under REACH, indicating lower regulatory restrictions compared to more hazardous chemicals. However, it must comply with workplace exposure limits, transportation regulations (ADR), and food additive regulations when used in food applications. Users must maintain safety data sheets and conduct appropriate risk assessments for workplace use.
