Application Areas
Industrial raw materials: mainly used for the production of nylon precursors such as adipic acid and caprolactam.
Solvent and extractant: used as solvents for rubber, coatings, and varnishes, and diluents for adhesives. Used for oil extraction, chromatographic analysis of standard substances, and organic synthesis.
Other uses: Widely used in industrial coatings, adhesives, organic synthesis and other fields
Storage conditions
Environmental requirements: Store in a cool, ventilated warehouse, away from sources of fire and heat. The storage temperature should not exceed 30 ℃, and the container should be kept sealed.
Isolation storage: Store separately from oxidants and prohibit mixing storage.
Safety facilities: Explosion proof lighting and ventilation equipment are used. Equip with leak emergency response equipment and firefighting equipment.
Safety precautions
Fire and explosion risks: Avoid contact with fire sources and prevent static electricity accumulation during transportation.
Health hazards: Long term exposure may cause damage to the central nervous system (headaches, dizziness, etc.) and skin and eye irritation. Wear protective equipment (such as gas masks and oil resistant gloves) during operation.
Emergency measures: ventilation and emergency treatment shall be taken immediately in case of leakage, and foam and carbon dioxide fire extinguishers shall be used in case of fire. Empty containers may contain harmful substances that need to be properly disposed of
