Propan-2-one

Propan-2-one is a colorless, volatile organic compound with the molecular formula C3H6O and CAS number 67-64-1. Also known as acetone or dimethyl ketone, it is the simplest ketone with a molecular weight of 58.08 g/mol. This flammable liquid is characterized by its distinctive sweet odor and complete miscibility with water. It serves as one of the most important industrial solvents and chemical intermediates in various manufacturing processes.

Propan-2-one is a colorless liquid with a characteristic sweet, pungent odor at room temperature. It has a low boiling point of 56°C and is highly volatile, making it readily evaporable. The substance is completely miscible with water and most organic solvents, including alcohols, ethers, and hydrocarbons. Its high volatility and excellent solvent properties, combined with its relatively low toxicity compared to other ketones, make it particularly valuable in industrial applications.

Propan-2-one serves as a versatile industrial solvent for paints, coatings, adhesives, and cleaning products. It is extensively used in the pharmaceutical industry for drug synthesis and purification processes. The chemical industry employs it as an intermediate in producing methyl methacrylate, bisphenol A, and other chemicals. Additionally, it finds applications in nail polish removers, paint thinners, and as a degreasing agent in electronics manufacturing and precision cleaning operations.

Propan-2-one requires careful handling due to its flammable nature and potential health effects. Use appropriate personal protective equipment including safety goggles, nitrile gloves, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and avoid ignition sources such as open flames, hot surfaces, and static electricity. Work in well-ventilated areas or under fume hoods, and have fire extinguishing equipment readily available. Avoid prolonged skin contact and inhalation of vapors.

Propan-2-one must be stored in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Use appropriate containers made of compatible materials such as steel or glass, ensuring they are tightly sealed to prevent evaporation. Store separately from strong oxidizing agents, acids, and bases to prevent dangerous reactions. Maintain storage temperatures below 25°C and ensure proper grounding of containers to prevent static electricity buildup during handling.

Propan-2-one contact requires immediate action depending on the exposure route. For skin contact, remove contaminated clothing and rinse affected areas with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing difficulties occur. For ingestion, do not induce vomiting and seek immediate medical attention while rinsing the mouth with water.

Propan-2-one disposal must comply with local environmental regulations as it is classified as hazardous waste. Small quantities can be recovered through distillation for reuse, while contaminated material requires disposal through licensed hazardous waste contractors. Never dispose of it down drains or into soil, as it can contaminate water sources. Empty containers should be handled as hazardous waste unless properly cleaned and decontaminated according to local regulations and waste management guidelines.

Propan-2-one is classified under ADR as Class 3 (flammable liquid), Packing Group II, requiring specific transport regulations. Containers must meet UN specification standards and display appropriate hazard labels including the flammable liquid pictogram. Transportation vehicles need proper ventilation, grounding equipment, and emergency response information. Drivers must have appropriate training and certification for dangerous goods transport. Quantities exceeding specified limits require additional documentation and safety measures according to European transport regulations.

Propan-2-one is regulated under European REACH and CLP regulations, requiring registration for quantities above one tonne per year. It is classified with hazard statements H225 (highly flammable liquid), H319 (causes serious eye irritation), and H336 (may cause drowsiness). The substance is not listed as a SVHC (Substance of Very High Concern) under REACH. Workplace exposure limits apply in most European countries, and specific safety data sheets must accompany shipments to ensure proper handling and compliance.
