1-Butanol stands out as a four-carbon alcohol with the chemical formula C4H10O. The structure, often shown as CH3(CH2)3OH, carries a straight-chain backbone. In daily work with chemicals, 1-Butanol comes up frequently due to its versatility. It arrives as a clear, colorless liquid with a strong, sweet odor. A quick dip into history reveals people have known about this molecule since the 19th century, but large-scale work only took off with modern chemical manufacturing. The Harmonized System (HS) Code usually used for international trade in 1-Butanol is 29051300, which sorts it among primary aliphatic alcohols.
Breaking things down to the molecular level, each 1-Butanol molecule has a simple linear arrangement. One end features a hydroxyl group; the long alkyl chain extends from there. This layout means it mixes well with many organic solvents, but shows only limited water solubility. Density sits around 0.81 g/cm³ at room temperature. Purity and spectral specifications often need close checking in laboratories, since contaminants alter properties or outcomes in many applications. Boiling point hovers near 118°C, melting point close to -89°C, providing a window between liquid and solid forms for storage and transport.
1-Butanol most often appears as a liquid. With time spent in chemical storage rooms, one knows plastic or metal containers are common—glass stays unused due to breakage risks. Powder, flake, crystal, or pearl forms don’t exist for pure 1-Butanol since it melts below anything near room temperature, so the liquid dominates all bulk storage and handling. Sometimes solutions are made for lab use, but the raw material itself stays in liquid state in drums or IBC totes. One liter of 1-Butanol weighs just over 800 grams, which matters when filling containers or measuring out precise quantities for mixtures.
Workplace safety rules treat 1-Butanol seriously due to its health risks. The vapor can irritate the respiratory tract; splashes in the eye sting and cause harm. When working without proper ventilation, headaches or dizziness creep up from inhaled fumes. Direct contact with the skin dries it out or even causes inflammation with repeated exposure. Fire hazards can’t be ignored, either. 1-Butanol catches fire easily—flash point hovers near 35°C, so heat or open sparks around it lead to danger. The safety sheet recommends goggles, gloves, and secure storage away from oxidizing agents. In closed workplaces, exhaust fans and routine air quality checks become habits to keep folks safe.
Industrial chemists frequently use 1-Butanol as a building block. Its carbon backbone lets it slip into esters, which later become flavors or fragrances. Feedstock supply chains rely on it for producing butyl acrylate, a key monomer for paints, adhesives, and sealants. Solvent users prefer 1-Butanol to dissolve resins or dyes where stronger, more aggressive choices would harm fine details of the finished products. Its moderate polarity, unique among alcohols, allows it to bridge gaps between petrochemical and biobased feedstocks without major reformulation. Sometimes detergent blends call for 1-Butanol as a wetting agent or intermediate, especially in textile processing or fiber finishing, where clean rinsing qualities help maintain product consistency.
Meeting quality expectations requires looking at more than just purity. Water content, color index, acidity, and the presence of aldehydes all influence the performance of 1-Butanol in paint, ink, or synthetic polymer lines. Certified batches come with detailed certificates of analysis, showing each value falls within tight ranges. In regulated markets, inspectors double-check transport labels and hazard markings, which must match international requirements to prevent shipment delays or safety mishaps at receiving docks. Storage temperature, venting, and drum labeling go into every shipment, so users don’t wrestle with confusion or mix-ups at the point of use.
Spills of 1-Butanol in the workplace or outdoors threaten soil and water. The compound breaks down in air over several days, but runoff contaminates streams and aquatic life. Efforts to contain spills quickly, neutralize vapors, and ventilate enclosed areas prove vital. Handling 1-Butanol with respect for both human health and the environment underpins every responsible operation, from large-scale refineries to small research labs. Companies invest in worker training, spill kits, and ongoing reviews of their chemical management policies. Safe disposal routes depend on local and national laws, which can include incineration or treatment in hazardous waste facilities.
