Methyl acetate

Methyl acetate is an organic chemical compound with the molecular formula C3H6O2 and CAS number 79-20-9. It belongs to the ester family and has a molecular weight of 74.08 g/mol. This substance is classified as a flammable liquid and poses specific safety risks including eye irritation and potential effects on the central nervous system, requiring careful handling in industrial applications.

Methyl acetate is a colorless, volatile liquid with a characteristic fruity, sweet odor reminiscent of glue or nail polish remover. It has excellent solvent properties and is miscible with most organic solvents including alcohols, ethers, and ketones. The compound has a relatively low boiling point, making it highly volatile at room temperature, and demonstrates good chemical stability under normal storage conditions.

Methyl acetate is primarily used as a solvent in various industrial applications including paint formulations, adhesives, and cleaning products. It serves as an excellent solvent for nitrocellulose, resins, oils, and fats. The compound is also utilized in the production of artificial leather, textile processing, and as a chemical intermediate in organic synthesis processes within the pharmaceutical and chemical industries.

Methyl acetate requires careful handling due to its flammable nature and potential health effects. Always wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and eliminate all ignition sources. Use explosion-proof electrical equipment and ground all containers during transfer operations. Avoid prolonged exposure and inhalation of vapors.

Methyl acetate should be stored in a cool, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed and use appropriate fire-resistant storage facilities. The storage area must be equipped with proper ventilation systems and fire suppression equipment. Store away from oxidizing agents and incompatible materials, and ensure containers are properly grounded to prevent static electricity buildup.

In case of eye contact with methyl acetate, immediately flush with plenty of clean water for at least 15 minutes and seek medical attention. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. 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 care.

Methyl acetate must be disposed of according to local and national waste regulations as a hazardous chemical waste. Contact licensed waste disposal companies specialized in handling flammable solvents. Never dispose of this substance through regular drainage systems or household waste. Small quantities should be allowed to evaporate in a well-ventilated area away from ignition sources, while larger amounts require professional hazardous waste treatment facilities.

Methyl acetate is classified as ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport regulations. Use UN-approved packaging and ensure proper labeling with appropriate hazard placards. Transport vehicles must be equipped with proper safety equipment and drivers require ADR certification. Avoid transport during extreme temperatures and ensure adequate ventilation in transport vehicles to prevent vapor accumulation.

Methyl acetate is regulated under European REACH and CLP regulations, requiring safety data sheets and proper hazard communication. It is not classified as a Substance of Very High Concern (SVHC). The substance must be handled according to occupational exposure limits and workplace safety regulations. Industrial users must comply with emission standards and environmental protection requirements specific to volatile organic compounds in their respective countries.
