Butane-1,4-diamine

Butane-1,4-diamine is an organic chemical compound with the molecular formula C4H12N2 and CAS number 110-60-1. It belongs to the diamine family, featuring two amino groups (-NH2) positioned at opposite ends of a four-carbon chain. With a molecular weight of 88.15 g/mol, this aliphatic diamine serves as an important building block in various chemical synthesis processes and industrial applications.

Butane-1,4-diamine is typically a colorless to pale yellow liquid or crystalline solid at room temperature, depending on purity and conditions. It exhibits high water solubility due to its polar amino groups and can form hydrogen bonds. The compound has a characteristic amine odor and is hygroscopic, readily absorbing moisture from air. Its dual amino functionality makes it highly reactive with acids and electrophiles.

Butane-1,4-diamine is primarily used as a building block in polymer synthesis, particularly for producing polyamides, polyurethanes, and epoxy curing agents. It serves as an intermediate in pharmaceutical manufacturing and fine chemical synthesis. The compound is also utilized in the production of corrosion inhibitors, fuel additives, and specialty chemicals. Its bifunctional nature makes it valuable for crosslinking applications in various industrial processes.

Butane-1,4-diamine should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Avoid contact with skin and eyes as diamines can cause irritation. Use non-sparking tools and ensure proper grounding when transferring the material to prevent static electricity buildup.

Butane-1,4-diamine should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep away from strong acids, oxidizing agents, and reactive chemicals. Store in original containers with proper labeling and ensure containers are made of compatible materials. Maintain storage temperature below 25°C and protect from moisture to prevent degradation and maintain product quality.

In case of skin contact with butane-1,4-diamine, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Butane-1,4-diamine must be disposed of according to local and national waste regulations as it cannot be discharged into sewers or the environment. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may be neutralized with appropriate acids under controlled conditions before disposal. Always consult local environmental authorities and follow waste classification codes for chemical waste management.

Butane-1,4-diamine is classified under ADR regulations as Class 4.1 (Flammable solids), Packing Group II, indicating it requires specific transport precautions. Use appropriate UN-approved packaging and ensure proper labeling with hazard diamonds and identification numbers. Transport vehicles must comply with ADR requirements including equipment and driver training. Consult current transport regulations and use certified dangerous goods carriers for shipment.

Butane-1,4-diamine is subject to REACH regulation in Europe, requiring registration for manufacture or import above certain tonnages. It must be classified and labeled according to CLP regulation, though it currently shows no specific GHS pictogrammes or signal words. The substance is not listed as SVHC (Substance of Very High Concern). Always verify current regulatory status and comply with local chemical management requirements.
