Cyclohexanamine

Cyclohexanamine is an organic compound with the chemical formula C6H13N and CAS number 108-91-8. It is a primary amine derived from cyclohexane, featuring a six-membered saturated carbon ring with an amino group (-NH2) attached. With a molecular weight of 99.17 g/mol, cyclohexanamine is classified as a hazardous substance requiring careful handling due to its flammable, toxic, and corrosive properties.

Cyclohexanamine is a colorless to pale yellow liquid at room temperature with a strong, fishy ammonia-like odor. It is moderately soluble in water and miscible with most organic solvents including alcohols and ethers. The compound has a boiling point around 134°C and is lighter than water. Its basic nature (pKa ~10.6) makes it capable of forming salts with acids, and it readily absorbs moisture from air.

Cyclohexanamine serves primarily as an intermediate in chemical synthesis and industrial manufacturing. It is widely used in the production of nylon 6,6 precursors, rubber accelerators, and corrosion inhibitors. The compound also finds applications in the manufacture of pharmaceuticals, agrochemicals, and specialty chemicals. Additionally, it serves as a curing agent for epoxy resins and as a chemical intermediate in various organic synthesis processes.

Cyclohexanamine requires strict safety measures including wearing chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing, as the substance is corrosive and can cause severe burns. Keep away from heat sources, sparks, and open flames due to its flammable nature. Emergency shower and eyewash facilities should be readily accessible.

Cyclohexanamine must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Keep containers in secondary containment to prevent spills and avoid storage near incompatible materials such as strong acids, oxidizing agents, and reactive metals. Storage areas should be equipped with appropriate fire suppression systems and maintain temperatures below 25°C to prevent vapor buildup and degradation.

Immediate action is required for cyclohexanamine exposure. For skin contact, remove contaminated clothing and flush affected areas with plenty of water for at least 15 minutes, then seek medical attention. If eyes are affected, rinse continuously with water for 15-20 minutes and remove contact lenses if present. For inhalation, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical care.

Cyclohexanamine disposal must comply with local and national hazardous waste regulations. The substance should never be poured down drains or disposed of with regular waste. Arrange disposal through licensed hazardous waste contractors who can properly treat or incinerate the material at authorized facilities. Small quantities may require neutralization before disposal, but this should only be done by trained personnel following established protocols and regulatory requirements.

Cyclohexanamine is classified under ADR as Class 8 (corrosive substances), Packing Group II, requiring specialized transportation procedures. It must be packaged in UN-approved containers with proper labeling including corrosive and flammable hazard markings. Transportation requires appropriate documentation, driver training, and emergency response information. Vehicles must be equipped with suitable fire extinguishers and spill control materials, and drivers must hold valid ADR certification for dangerous goods transport.

Cyclohexanamine is subject to comprehensive chemical regulations including REACH registration in Europe and CLP classification requirements. It is classified as Repr. 2 (reproductive toxicity), requiring special handling and labeling with GHS08 health hazard pictograms. The substance may be subject to workplace exposure limits and requires safety data sheets for commercial supply. Users must comply with industrial emissions regulations and may need permits for storage and use in certain quantities.
