Hexane

Hexane is a saturated hydrocarbon with the molecular formula C6H14 and CAS number 110-54-3. It belongs to the alkane family and has a molecular weight of 86.18 g/mol. This chemical compound is classified as a flammable liquid with significant health hazards including reproductive toxicity, aspiration toxicity, and organ damage potential. Hexane requires careful handling due to its dangerous properties.

Hexane is a colorless liquid with a gasoline-like odor at room temperature. It has a low boiling point and high volatility, making it easily evaporable. The substance is highly flammable and practically insoluble in water but miscible with most organic solvents. Its low viscosity and non-polar nature make it an excellent solvent for extracting oils and fats from various materials.

Hexane is primarily used as an industrial solvent for extracting vegetable oils from seeds and nuts in food processing. It serves as a cleaning agent for removing grease and oil in manufacturing processes, and as a laboratory solvent for chromatography and extraction procedures. Additionally, hexane is used in the production of adhesives, textiles, and as a component in some specialty chemical formulations.

Hexane requires strict safety measures including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Eliminate all ignition sources as hexane vapors can ignite easily. Avoid skin contact and ensure emergency shower and eyewash stations are readily accessible during handling operations.

Hexane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Use only approved containers and storage cabinets designed for flammable liquids. Keep containers tightly sealed to prevent vapor escape and store away from incompatible materials such as strong oxidizing agents. Maintain storage temperature below 25°C and implement appropriate fire suppression systems in storage areas.

Hexane exposure requires immediate action: for skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately and provide respiratory support if needed. For ingestion, do not induce vomiting due to aspiration hazard and seek immediate medical care.

Hexane disposal must comply with local and national hazardous waste regulations as it cannot be disposed of with regular waste. The substance should be collected in appropriate containers and handed over to licensed hazardous waste disposal companies. Never pour hexane down drains or sewers, and avoid evaporation into the atmosphere. Consider recovery and recycling options where economically viable to minimize environmental impact.

Hexane is classified under ADR Class 3 (flammable liquids) Packing Group II, requiring specific transport regulations compliance. Use UN-approved packaging and ensure proper hazard labeling with appropriate placarding on transport vehicles. Drivers must hold ADR certification for dangerous goods transport. Vehicles should be equipped with appropriate fire extinguishers and emergency equipment, and routes should avoid populated areas where possible.

Hexane is subject to comprehensive European chemical regulations under REACH and CLP classifications. It carries multiple hazard classifications including reproductive toxicity (Repr. 2) and specific target organ toxicity (STOT RE 1), requiring detailed safety data sheets and risk assessments. While not currently listed as a SVHC substance, its hazardous properties mandate strict workplace exposure limits and comprehensive risk management measures.
