Butanal

Butanal is an organic aldehyde with the molecular formula C4H8O and CAS number 123-72-8. It has a molecular weight of 72.11 g/mol and belongs to the family of saturated aliphatic aldehydes. This chemical compound is classified as a flammable liquid (Flam. Liq. 2) under GHS regulations, requiring careful handling due to its fire hazard properties. Butanal appears as a colorless liquid with a characteristic aldehyde odor and is commonly used in various industrial applications.

Butanal is a colorless liquid with a pungent, characteristic aldehyde odor at room temperature. It has a molecular formula of C4H8O and a molecular weight of 72.11 g/mol. The compound is moderately soluble in water and miscible with most organic solvents including alcohols and ethers. Butanal has a relatively low boiling point and high volatility, contributing to its classification as a flammable liquid. Its aldehyde functional group makes it reactive toward nucleophiles and oxidizing agents.

Butanal is primarily used as an intermediate in organic synthesis and chemical manufacturing processes. It serves as a precursor for the production of various chemicals including butanoic acid, alcohols, and other aldehydes through oxidation or reduction reactions. The compound is utilized in the pharmaceutical industry for synthesizing active ingredients and in the production of fragrances and flavoring agents. Additionally, butanal finds applications in polymer chemistry and as a solvent in specialized industrial processes.

Butanal requires careful handling due to its flammable nature (Flam. Liq. 2, Danger signal word). Always wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume hoods to prevent vapor accumulation. Eliminate all ignition sources including open flames, hot surfaces, and electrical equipment that could generate sparks. Use explosion-proof equipment when transferring or processing the material. Ensure emergency shower and eyewash stations are readily accessible.

Butanal 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 and ensure they are properly sealed to prevent vapor escape. Store separately from strong oxidizing agents, acids, and bases to avoid incompatible reactions. Maintain storage temperatures below the compound's flash point and implement proper fire prevention measures including appropriate fire suppression systems. Follow local fire codes and chemical storage regulations.

Butanal contact requires immediate first aid measures depending on the exposure route. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush eyes with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately and monitor for respiratory distress. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for specific guidance.

Butanal disposal must comply with local, national, and international waste regulations due to its flammable classification. The compound should be treated as hazardous waste and disposed of through licensed waste management facilities capable of handling flammable liquids. Small quantities may be incinerated in appropriate high-temperature facilities with proper emission controls. Never dispose of butanal down drains or in regular waste streams. Contact certified waste disposal companies for proper collection and treatment. Maintain disposal records as required by regulations.

Butanal is classified under ADR regulations as Class 3 (flammable liquids), Packing Group II, requiring specific transport protocols. The compound must be packaged in UN-approved containers suitable for flammable liquids and properly labeled with appropriate hazard markings. Transport vehicles must comply with ADR requirements for Class 3 substances including proper ventilation, fire extinguishing equipment, and driver certification. Shipping documentation must include proper shipping names, hazard classifications, and emergency response information. Only use authorized carriers experienced in hazardous materials transport.

Butanal is subject to various chemical regulations including REACH registration requirements in the European Union and CLP classification as Flam. Liq. 2 with GHS02 pictogram and Danger signal word. The compound is not currently listed as a Substance of Very High Concern (SVHC) under REACH. Users must comply with workplace safety regulations, environmental protection laws, and transport regulations (ADR Class 3). Industrial users may need to implement risk management measures and maintain safety data sheets. Always verify current regulatory status before use.
