3.Molecular Formula:C6H11NO
4.UN No.:2811
5.HS No.:2933710000
6.CAS No.: 105-60-2
7.EINECS No.: 203-313-2
9.Purity:≥99.8%
10.Appearance:White flakes
Physical and Chemical Properties
1. Appearance: White crystalline powder or plate-like crystals at room temperature, with a mildly pungent odor
2. Melting Point: 68–70°C; melts into a colorless transparent liquid when heated above this point
3. Boiling Point: 270°C (at atmospheric pressure); decomposes when temperature exceeds 300°C
4. Solubility: Highly soluble in water (solubility ~100g/100mL at 25°C), soluble in ethanol, diethyl ether, benzene, and most organic solvents
5. Density: Crystalline state density 1.02g/cm³, liquid density 0.96g/cm³ (70°C)
6. Hygroscopicity: Highly hygroscopic; readily absorbs moisture and caking occurs when exposed to humid air
7. Chemical Stability: Stable at room temperature; reacts with acids to form salts; undergoes hydrolysis with alkalis upon heating to produce aminohexanoic acid; combustible; releases toxic nitrogen oxides upon combustion
Application
1. Textile Fiber Sector (65% share): As the core monomer for synthetic nylon 6 fibers, it is used to produce apparel fabrics, industrial textiles, fishing nets, and other applications. It remains a critical imported raw material following the relocation of Southeast Asia’s textile industry.
2. Engineering Plastics Sector (20% share): Used to produce nylon 6 engineering plastics for automotive lightweight components, electronic enclosures, and mechanical gears, aligning with European and American automakers’ emissions reduction requirements.
3. Coatings/Adhesives Sector (10% share): Synthesizes polyamide resins for high-end anti-corrosion coatings and hot-melt adhesives, with robust procurement demand from Middle Eastern infrastructure projects.
4. Other Sectors (5% share): Serves as pharmaceutical intermediates or moisturizing agents in premium Japanese and Korean cosmetics, with custom orders commanding 15%-20% premium pricing.
Storage
1. Storage Environment: Store in a cool, dry, well-ventilated warehouse with temperature controlled below 25°C and relative humidity ≤60%. Keep away from open flames and heat sources (minimum distance ≥30m).
2. Packaging Protection: Maintain intact packaging seals (vacuum bags/sealed drums) to prevent direct air contact and moisture absorption causing caking. Strictly prohibit outdoor stacking or placement near damp walls.
3. Storage Restrictions: Do not store with oxidizers, strong acids, strong alkalis, or other incompatible chemicals. Store in separate zones with clear isolation signage. Keep away from food, beverages, and other consumer goods.
4. Warehouse Management: Regularly inspect packaging for damage or leaks. Immediately isolate and handle any moisture-absorbed or caked material. Equip storage areas with dehumidification equipment and emergency spill response tools.
