1-Octane is a chemical substance that belongs to isomers with a molecular formula of C8H18, of which n-octane and isooctane are the two most common types.
n-Octane, with a chemical formula of CH3(CH2)6CH3, is a colorless, transparent liquid with a low boiling point and a high flash point. Due to its stability, it is widely used as a fuel, especially in fuels for vehicles such as cars and airplanes. n-Octane produces high energy when burned and does not produce harmful substances, and is considered to be a more environmentally friendly fuel. In addition, n-octane can also be used as a printing ink solvent, a solvent for butyl rubber, and a solvent and synthetic raw material for organic reactions.

Hazardous characteristics:
Flammable, its vapor is heavier than air. It can form explosive mixture with air. Keep away from fire.
Health hazards: Irritating to skin. Long-term contact through inhalation can cause serious harm. Ingestion is harmful to the lungs, and its vapor can cause coma.
Environmental hazards: Highly toxic to aquatic organisms and can cause long-term adverse effects.
Explosion hazard: Highly flammable
Operation and storage:
Operation precautions: Closed operation, comprehensive ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), safety glasses, anti-static work clothes, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor from leaking into the workplace air. Avoid contact with oxidants. The flow rate should be controlled during filling, and there should be a grounding device to prevent static electricity accumulation. Load and unload gently during transportation to prevent damage to the packaging and containers. Equip with appropriate types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may have harmful residues.
Storage precautions: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 30℃. Keep the container sealed. It should be stored separately from oxidants and should not be mixed. Use explosion-proof lighting and ventilation facilities. Mechanical equipment and tools that are prone to sparks are prohibited. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
Transportation precautions:
The packaging should be complete and the loading should be safe when it is shipped. During transportation, ensure that the container does not leak, collapse, fall, or be damaged. It is strictly forbidden to mix and transport with oxidants. During transportation, it should be protected from exposure to sunlight, rain, and high temperature. During transportation, the transport vehicle should be equipped with appropriate types and quantities of fire-fighting equipment and leakage emergency treatment equipment. The exhaust pipe of the vehicle carrying this product must be equipped with a fire-blocking device. When stopping in the middle of the journey, it should be kept away from fire and heat sources. It is forbidden to slide during railway transportation.
