Operation precautions : closed operation, full ventilation. Operators must be specially trained and strictly abide by operating procedures. It is recommended that operators wear a filter type gas mask (half mask), safety protective glasses, anti-static clothes, and rubber oil-resistant gloves. Keep away from fire, heat source, no smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from escaping into the workplace air. Avoid contact with oxidants, acids and bases. The flow rate should be controlled during filling, and there should be a grounding device to prevent electrostatic accumulation. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. An empty container may contain harmful residue.
Storage precautions : Usually the commodity has an inhibitor. Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the warehouse should not exceed 30ºC. The package should be sealed and not in contact with air. It should be stored separately from oxidizers, acids and bases, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.

Mainly used as solvent, chemical synthesis intermediate, analytical reagent.
