Ethenyl acetate

Ethenyl acetate is an organic chemical compound with the molecular formula C4H6O2 and CAS number 108-05-4. It has a molecular weight of 86.09 g/mol and belongs to the acetate ester family. This substance is classified as a flammable liquid with carcinogenic properties, requiring careful handling due to its hazardous nature. It appears as a colorless liquid with a characteristic sweet odor and is widely used in industrial applications for polymer production.

Ethenyl acetate is a colorless, volatile liquid with a sweet, fruity odor characteristic of acetate esters. It has a molecular weight of 86.09 g/mol and is moderately soluble in water while being fully miscible with most organic solvents. The compound exhibits high volatility at room temperature and is highly flammable. Its chemical structure makes it reactive toward polymerization, especially under heat or in the presence of catalysts.

Ethenyl acetate is primarily used as a monomer in the production of polyvinyl acetate (PVA) and various copolymers. It serves as a key raw material in manufacturing adhesives, paints, coatings, and textile finishes. The compound is also utilized in the production of chewing gum base, paper coatings, and as an intermediate in organic synthesis. Its polymerization properties make it valuable for creating films, fibers, and other plastic materials in industrial applications.

Ethenyl acetate requires strict safety protocols due to its flammable and carcinogenic properties. Workers must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Handle only in well-ventilated areas or under fume hoods to prevent inhalation. Eliminate all ignition sources as the substance is highly flammable. Use grounding and bonding techniques during transfer operations to prevent static electricity buildup and potential fire hazards.

Ethenyl acetate must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use only approved containers and keep them tightly sealed to prevent vapor escape. Store separate from strong oxidizing agents, acids, and bases to avoid dangerous reactions. Maintain storage temperature below 25°C and implement fire suppression systems. Regular inspection of containers for leaks or damage is essential due to the substance's volatile and flammable nature.

Immediate action is required upon contact with ethenyl acetate. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult emergency services for serious exposures.

Ethenyl acetate disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance cannot be discharged into sewers, waterways, or regular waste streams. Contact licensed hazardous waste disposal companies for proper treatment, which typically involves incineration at high temperatures in specialized facilities. Small quantities may be recovered through distillation if economically viable. Always maintain proper documentation of disposal activities as required by environmental authorities.

Ethenyl acetate is classified under ADR Class 3 (Flammable Liquids), Packing Group II, requiring specialized transport procedures. Use only UN-approved packaging and containers specifically designed for flammable liquids. Vehicles must carry appropriate fire extinguishing equipment and emergency response information. Drivers need ADR certification for dangerous goods transport. Ensure proper labeling with GHS02, GHS07, and GHS08 pictograms and 'Danger' signal word during shipping throughout Europe.

Ethenyl acetate is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification as Flam. Liq. 2, Carc. 2, Acute Tox. 4, and STOT SE 3. It requires safety data sheets and proper labeling with danger pictograms. While not currently listed as an SVHC substance, its carcinogenic classification means potential future restrictions. Industrial users must implement risk management measures and may need authorization for certain uses under REACH regulations.
