Ethenyl propanoate

Ethenyl propanoate is an organic chemical compound with the molecular formula C5H8O2 and CAS number 105-38-4. This vinyl ester has a molecular weight of 100.12 g/mol and belongs to the class of unsaturated carboxylic acid esters. It features a vinyl group (ethenyl) attached to a propanoate moiety, making it a reactive monomer commonly used in polymer chemistry and industrial applications.

Ethenyl propanoate is a clear, colorless liquid at room temperature with a characteristic sweet, fruity odor. It has limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound is highly reactive due to its vinyl group, making it susceptible to polymerization reactions. It has a relatively low boiling point and moderate volatility at ambient conditions.

Ethenyl propanoate is primarily used as a monomer in the production of polyvinyl esters and copolymers. It serves as a key intermediate in the manufacture of adhesives, coatings, and textile finishes. The compound is also utilized in the synthesis of specialty polymers for packaging materials and as a crosslinking agent in various industrial formulations. Its reactivity makes it valuable for producing materials with specific mechanical properties.

Ethenyl propanoate requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction systems to avoid inhalation of vapors. Avoid contact with heat sources, sparks, and open flames as the compound is flammable. Use non-sparking tools and ensure proper grounding of equipment during transfer operations.

Ethenyl propanoate must be stored in cool, dry, well-ventilated areas away from heat sources and direct sunlight. Keep containers tightly sealed in original packaging and store below 25°C to prevent unwanted polymerization. Separate from strong oxidizing agents, acids, and bases. Use appropriate fire prevention measures and ensure storage areas comply with local regulations for flammable liquids. Regular inventory rotation is recommended to maintain product quality.

Ethenyl propanoate contact requires immediate action depending on exposure route. For skin contact, remove contaminated clothing and wash 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 to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention while providing safety data sheet information.

Ethenyl propanoate disposal must comply with local and national waste management regulations as a flammable organic waste. Contact licensed waste disposal companies specialized in handling chemical waste for proper treatment. Do not discharge into sewers, waterways, or soil. Small quantities can be incinerated in approved facilities with adequate emission controls. Always consult local environmental authorities for specific disposal requirements and maintain proper waste documentation.

Ethenyl propanoate is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specialized transport procedures. Use UN-approved packaging and ensure proper labeling with hazard diamonds and transport documentation. Vehicles must comply with ADR regulations including appropriate fire extinguishing equipment and driver certification. Avoid transport during extreme temperatures and ensure adequate ventilation. Follow specific routing restrictions for dangerous goods where applicable.

Ethenyl propanoate is regulated under European REACH legislation requiring registration for import/manufacture above one tonne annually. It falls under CLP regulation for classification and labeling of chemical substances. Transport is governed by ADR/RID regulations for dangerous goods. While not currently listed as a Substance of Very High Concern (SVHC), manufacturers and users must comply with standard industrial chemical safety requirements and workplace exposure limits.
