Product Uses

Mainly used in organic synthesis, and can also be used as a solvent and a comparative sample for gas chromatography.

Hazardous Characteristics:

Its vapor can form an explosive mixture with air. It can cause combustion and explosion when exposed to open flames and high heat. It can cause combustion and explosion when exposed to strong oxidants. It can cause combustion and explosion when exposed to strong oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower level. It can ignite backfire when exposed to open flames.

Fire Extinguishing Methods:

Spray water to cool the container, and if possible, move the container from the fire scene to an open area. If the container in the fire scene has changed color or a sound is produced from the safety pressure relief device, it must be evacuated immediately. Fire extinguishing agents: foam, carbon dioxide, dry powder, sand and soil. Fire extinguishing with water is ineffective.

Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate it, and strictly restrict entry and exit. Cut off the source of fire. Recommendations

Emergency treatment of leaks:

Emergency treatment personnel wear self-contained positive pressure respirators and fire protection clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drainage ditches. Small leakage: absorb with sand, vermiculite or other inert materials. Then transport to an open area for burial, evaporation, or incineration. Large leakage: build a dike or dig a pit to contain; cover with foam to reduce vapor hazards. Use an explosion-proof pump to transfer to a tank truck or a special collector, recycle or transport to a waste disposal site for disposal.

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The temperature in the warehouse should not exceed 30℃. Prevent sunlight

Storage and transportation precautions:

Direct sunlight. Keep the container sealed. It should be stored separately from oxidants. Lighting, ventilation and other facilities in the storage room should be explosion-proof, and the switch should be set outside the warehouse. Fire and explosion prevention technical measures should be taken when storing in tanks. Mechanical equipment and tools that are prone to sparks are prohibited. Pay attention to the flow rate (no more than 3m/s) when filling, and have a grounding device to prevent static electricity accumulation. Load and unload gently during transportation to prevent damage to the packaging and containers.
