Ethyl acetate

Ethyl acetate is an organic chemical compound with the molecular formula C4H8O2 and CAS number 141-78-6. It is an ester formed from ethanol and acetic acid, with a molecular weight of 88.11 g/mol. This colorless liquid is classified as a flammable liquid (Class 2) and carries danger warnings due to its eye irritation properties and specific target organ toxicity. It is widely used as a solvent in various industrial applications and is recognized by its characteristic sweet, fruity odor reminiscent of nail polish remover.

Ethyl acetate is a colorless, volatile liquid with a characteristic sweet, fruity odor. It has a molecular weight of 88.11 g/mol and boils at approximately 77°C. The compound is moderately soluble in water (about 8.3% at 20°C) but miscible with most organic solvents including alcohols, ethers, and hydrocarbons. It has a relatively low viscosity and density of about 0.9 g/cm³. Its high volatility and low boiling point make it an excellent solvent that evaporates quickly at room temperature.

Ethyl acetate is primarily used as a solvent in various industrial applications including paints, coatings, inks, and adhesives. It serves as an extraction solvent in pharmaceutical manufacturing and food processing industries. The compound is widely used in nail polish removers and other cosmetic products due to its effective dissolving properties and relatively low toxicity. It also finds applications in the production of artificial flavors, decaffeination of coffee and tea, and as a cleaning agent in electronics manufacturing.

Ethyl acetate must be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing to prevent eye and skin contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Due to its flammable nature (Flam. Liq. 2), eliminate all ignition sources and use explosion-proof equipment. Avoid static electricity buildup and ensure proper grounding of containers. Emergency shower and eyewash facilities should be readily accessible when working with this substance.

Ethyl acetate should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its flammable classification (Class 3, Group II). Use only approved containers and keep them tightly sealed to prevent vapor release. Storage areas must be equipped with appropriate fire suppression systems and maintained below 25°C when possible. Keep away from oxidizing agents and strong acids or bases. Ensure adequate spacing between containers and provide proper secondary containment to prevent spill spread.

In case of skin contact with ethyl acetate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a healthcare professional after significant exposure incidents.

Ethyl acetate must be disposed of according to local, national, and international environmental regulations as hazardous waste. The substance cannot be discharged into sewers, waterways, or soil. Contact licensed waste disposal companies for proper collection and treatment. Small quantities may be recovered through distillation for reuse. Contaminated materials like rags or absorbents should also be treated as hazardous waste. Always consult your local environmental authority for specific disposal requirements and approved disposal facilities in your region.

Ethyl acetate is classified under ADR as Class 3 (flammable liquids), Packing Group II, requiring specific transport regulations. It must be transported in UN-approved packaging with proper labeling including GHS02 and GHS07 pictograms and 'Danger' signal word. Vehicles must carry appropriate fire extinguishing equipment and drivers need ADR certification. Transport documents must include the proper shipping name, UN number, and emergency response information. Ensure adequate ventilation during transport and avoid exposure to heat sources or mechanical impacts that could cause container damage.

Ethyl acetate is regulated under various European legislations including REACH and CLP regulations. It must be classified and labeled according to CLP with pictograms GHS02 and GHS07, and the danger signal word due to its flammable and eye irritation properties. The substance is not currently listed as a Substance of Very High Concern (SVHC) under REACH. Industrial users must comply with workplace exposure limits and may need to prepare safety data sheets. Specific restrictions may apply depending on the intended use and concentration in mixtures.
