Butan-2-amine

Butan-2-amine is a primary aliphatic amine with the molecular formula C4H11N and CAS number 13952-84-6. It is a flammable liquid with corrosive properties, belonging to the class of short-chain alkyl amines. With a molecular weight of 73.14 g/mol, this chemical compound is characterized by an amino group attached to the second carbon of a butane chain, making it an isomer of butylamine with distinct chemical and physical properties.

Butan-2-amine is a colorless liquid at room temperature with a characteristic ammonia-like odor typical of aliphatic amines. As a low molecular weight amine, it exhibits good solubility in water and polar organic solvents due to its ability to form hydrogen bonds. The compound has a boiling point in the range typical for short-chain amines and displays basic properties in aqueous solution, forming salts with acids.

Butan-2-amine is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a building block for the production of various chemicals including pharmaceuticals, agrochemicals, and specialty chemicals. The compound is also utilized in the synthesis of surfactants, corrosion inhibitors, and as a catalyst or catalyst precursor in certain chemical reactions. Its amine functionality makes it valuable for creating nitrogen-containing compounds in industrial processes.

Butan-2-amine requires careful handling due to its flammable and corrosive nature. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. Eliminate ignition sources as the substance is classified as Flammable Liquid Category 2. Ground all equipment to prevent static electricity buildup during transfer operations.

Butan-2-amine must be stored in a cool, dry, well-ventilated area away from heat sources and ignition points. Use appropriate containers resistant to corrosive amines, typically stainless steel or suitable plastic materials. Keep containers tightly closed and avoid contact with acids, oxidizing agents, and incompatible materials. Storage areas should be equipped with appropriate fire suppression systems and emergency response equipment due to the flammable nature of the substance.

Butan-2-amine contact requires immediate action due to its corrosive properties. For skin contact, immediately flush with plenty of water for at least 15 minutes and remove contaminated clothing. In case of eye contact, rinse thoroughly with water for at least 15 minutes and seek immediate medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. For ingestion, do not induce vomiting and seek immediate medical care.

Butan-2-amine disposal must comply with local and national hazardous waste regulations due to its classification as flammable and corrosive. The substance should never be discharged into sewers or waterways due to its aquatic toxicity classification. Professional hazardous waste disposal services should handle the waste through approved methods such as incineration at licensed facilities. Small quantities may require neutralization before disposal, following appropriate safety protocols and regulatory guidelines.

Butan-2-amine is classified under ADR as Class 3 (flammable liquids), Packing Group II, indicating moderate danger level during transport. Transportation requires appropriate UN-approved packaging designed for flammable and corrosive substances. Vehicles must carry proper documentation, emergency response information, and appropriate safety equipment. Drivers require ADR training certification, and transport must follow designated routes with proper placarding and labeling according to dangerous goods regulations.

Butan-2-amine is subject to various chemical regulations including REACH registration requirements for manufacture and import in the European Union. The substance must comply with CLP regulation for classification and labeling, displaying appropriate GHS pictograms (GHS02, GHS07, GHS05, GHS09) and danger signal word. While not currently listed as a SVHC substance, it may be subject to workplace exposure limits and specific handling requirements depending on national legislation and intended use.
