Tetrahydrofuran, also known as oxygenated cyclopentane or 1,4-epoxybutane, is a heterocyclic organic compound with the chemical formula C4H8O. It belongs to the ether class and is a completely hydrogenated product of furan. It is a colorless and transparent liquid that is soluble in water, ethanol, ether, acetone, benzene, etc. It is mainly used as a solvent, chemical synthesis intermediate, and analytical reagent.
Precautions for operation: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear filter type gas masks (half face masks), safety goggles, anti-static work clothes, and rubber oil resistant gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidants, acids, and bases. During filling, the flow rate should be controlled and there should be a grounding device to prevent static electricity accumulation. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.
Storage precautions: Typically, products are added with polymerization inhibitors. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants, acids, bases, etc., and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.
