Acetyl acetate

Acetyl acetate is an organic chemical compound with the molecular formula C4H6O3 and CAS number 108-24-7. This substance has a molecular weight of 102.09 g/mol and belongs to the ester family. It is classified as a flammable liquid with corrosive properties and acute toxicity hazards, requiring careful handling in industrial applications.

Acetyl acetate is a colorless liquid with a characteristic ester-like odor at room temperature. As an ester compound with molecular formula C4H6O3, it exhibits typical organic solvent properties including flammability and volatility. The substance has moderate polarity, making it miscible with many organic solvents while having limited water solubility.

Acetyl acetate serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. It is commonly used as a solvent in industrial applications, particularly in the production of pharmaceuticals, agrochemicals, and specialty chemicals. The compound also finds use in laboratory research as a reagent for various chemical reactions and analytical procedures.

Acetyl acetate requires strict safety protocols due to its corrosive and toxic properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and respiratory system, and keep away from ignition sources due to its flammable nature.

Acetyl acetate must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition points. Storage areas should be equipped with appropriate fire suppression systems and secondary containment. Keep away from incompatible materials such as strong bases, oxidizing agents, and water-reactive substances to prevent dangerous reactions.

Immediate action is required for acetyl acetate exposure due to its corrosive properties. For skin contact, immediately remove contaminated clothing and flush with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move to fresh air and monitor breathing. Always consult medical professionals for any exposure incident.

Acetyl acetate disposal must comply with local and national hazardous waste regulations due to its classification as dangerous goods. The substance cannot be disposed of through regular waste streams and requires treatment by licensed hazardous waste disposal facilities. Neutralization or incineration at appropriate temperatures in specialized facilities is typically required, following all applicable environmental protection guidelines.

Acetyl acetate is classified as ADR Class 8 (corrosive substances), Packing Group II, requiring specialized dangerous goods transportation procedures. Packages must meet UN specification requirements and display appropriate hazard labels including corrosive and flammable liquid markings. Transport documents, emergency response information, and driver training for dangerous goods are mandatory for legal transportation across Europe.

Acetyl acetate is regulated under multiple European frameworks including CLP regulation for classification and labeling, and REACH regulation for chemical registration and authorization. The substance requires safety data sheets and proper hazard communication due to its Danger signal word classification. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH.
