Butane-1,4-diamine

Butane-1,4-diamine is an organic chemical compound with the molecular formula C4H12N2 and CAS number 110-60-1. This diamine features two amino groups (-NH2) positioned at each end of a four-carbon chain, making it a symmetric aliphatic diamine. With a molecular weight of 88.15 g/mol, it serves as an important building block in polymer chemistry and various industrial applications.

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

Butane-1,4-diamine is primarily used as a monomer in polyamide and polyurethane production, serving as a chain extender and cross-linking agent. It finds applications in the synthesis of specialty polymers, adhesives, and coatings. The compound is also utilized in pharmaceutical intermediates, corrosion inhibitors, and as a curing agent for epoxy resins in industrial formulations.

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 extraction to avoid inhalation of vapors. Avoid direct skin and eye contact, as amines can be irritating. Use non-sparking tools and ensure proper grounding when transferring the material to prevent static buildup.

Butane-1,4-diamine should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers away from oxidizing agents and acids to prevent unwanted reactions. Store below 25°C when possible and protect from moisture to maintain product quality. Ensure storage areas comply with local regulations for flammable materials (ADR Class 4.1).

In case of skin contact with butane-1,4-diamine, immediately remove contaminated clothing and rinse the affected area with plenty of water for at least 15 minutes. For eye contact, flush thoroughly with clean water and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical assistance. Always consult safety data sheets for complete first aid procedures.

Butane-1,4-diamine waste must be disposed of according to local and national hazardous waste regulations. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil. Small quantities may be neutralized under controlled conditions by qualified personnel, but commercial waste should always be handled by certified waste management services following applicable environmental legislation.

Butane-1,4-diamine is classified under ADR as Class 4.1 (Flammable Solids), Packing Group II, requiring appropriate dangerous goods packaging and documentation. Transport containers must be properly labeled and marked according to ADR regulations. Use UN-approved packaging suitable for Packing Group II materials. Ensure transport vehicles are equipped with appropriate safety equipment and drivers hold valid dangerous goods training certificates.

Butane-1,4-diamine is subject to standard REACH registration requirements in Europe and must comply with CLP classification and labeling regulations. The substance is not listed as an SVHC (Substance of Very High Concern) under REACH. Users must ensure proper risk assessment, safety data sheet distribution, and compliance with occupational exposure limits where established by local authorities.
