Pentan-3-one

Pentan-3-one is an organic ketone compound with the molecular formula C5H10O and CAS number 96-22-0. It belongs to the family of aliphatic ketones, featuring a carbonyl group positioned at the third carbon of a five-carbon chain. With a molecular weight of 86.13 g/mol, this substance is classified as a flammable liquid and is commonly used as an industrial solvent and chemical intermediate in various manufacturing processes.

Pentan-3-one is a colorless liquid at room temperature with a characteristic ketone odor. As a ketone with moderate polarity, it exhibits limited solubility in water but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a relatively low boiling point typical of C5 ketones and demonstrates good stability under normal storage conditions, making it suitable for various industrial applications.

Pentan-3-one serves primarily as an industrial solvent and chemical intermediate in manufacturing processes. It is utilized in the production of pharmaceuticals, agrochemicals, and specialty chemicals due to its excellent dissolving properties for organic compounds. The substance also finds applications in coating formulations, cleaning agents, and as a reaction medium in organic synthesis. Its moderate volatility and stability make it valuable in various industrial extraction and purification processes.

Safe handling of pentan-3-one requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and adequate ventilation due to its flammable nature. Work should be conducted away from ignition sources, heat, and sparks. The substance can cause specific target organ toxicity, so minimize inhalation and skin contact. Use explosion-proof electrical equipment in work areas and ensure proper grounding of containers during transfer operations to prevent static discharge.

Proper storage of pentan-3-one requires cool, dry, well-ventilated areas away from heat sources, sparks, and incompatible materials. Containers should be tightly sealed and stored in secondary containment to prevent spills. As a Class 3 flammable liquid, it must be kept away from oxidizing agents and strong acids. Storage areas should be equipped with appropriate fire suppression systems and maintained at temperatures below the flash point to minimize vapor formation.

Immediate first aid for pentan-3-one exposure involves removing contaminated clothing and flushing affected skin or eyes with plenty of water for at least 15 minutes. 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. Remove the person from the exposure area and provide supportive care while awaiting professional medical assistance.

Proper disposal of pentan-3-one must comply with local and national hazardous waste regulations as it is classified as flammable waste. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Incineration at approved high-temperature facilities is typically the preferred disposal method. Empty containers may still contain residues and require proper cleaning or disposal as hazardous waste according to local environmental regulations.

Transportation of pentan-3-one follows ADR Class 3 regulations for flammable liquids, Packing Group II. Proper UN-specification packaging is required, along with appropriate hazard labels and transport documentation. Vehicles must be equipped with appropriate safety equipment and drivers need hazardous materials certification. The substance requires proper segregation from incompatible materials during transport and must be secured to prevent movement and potential container damage during transit.

Pentan-3-one is regulated under various European chemical legislation including REACH registration requirements and CLP classification as a flammable liquid with specific target organ toxicity. It is not currently listed as a Substance of Very High Concern (SVHC). Companies handling this substance must comply with occupational health and safety regulations, environmental protection laws, and transport regulations. Proper safety data sheets and risk assessments are mandatory for commercial use.
