1.Tetrahydrofuran is used as a solvent and raw material for organic synthesis
2.Tetrahydrofuran is used as a chromatographic analysis reagent, organic solvent, and nylon intermediate
3.Tetrahydrofuran, also known as oxoalkanes, oxoalkanes, and tetramethylene oxide, is an intermediate in the synthesis of pesticide phenylbutyltin. 4.In addition, it can also be directly used to manufacture synthetic fibers, synthetic resins, and synthetic rubbers. Polymer materials, precision tapes, and solvents in the electroplating industry.
5.It is also used in the production of adipic nitrile, adipic acid, adipic diamine, succinic acid, butanediol γ- Butyrolactone and can be used in the pharmaceutical industry.
6.It is used in the production of Kebiqing, progesterone, rifampicin, and as a medicinal solvent.
7.THF is an important organic synthesis raw material and a solvent with excellent performance.
8.It is particularly suitable for dissolving polyvinyl chloride, polyvinylidene chloride, and butyl aniline.
9.It is widely used as a surface coating, anti-corrosion coating, printing ink, adhesive tape, and film coating for Chemicalbook.
10.The solvent is used as a reaction solvent, and when used in aluminum electroplating solutions, the thickness of the aluminum layer can be arbitrarily controlled and bright
Emergency measures
Skin contact:
Remove contaminated clothing and thoroughly rinse the skin with soap and water.
Eye contact:
Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.
Inhalation:
Quickly evacuate the scene to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.
Ingestion:
Drink plenty of warm water and induce vomiting. Seek medical attention.
Fire protection measures
Dangerous characteristics:
Its vapor can form explosive mixtures with air. Exposure to high heat, open flames, and strong oxidants can easily cause combustion. Exposure to air or exposure to light can generate peroxides with potential explosive hazards. Reactions can occur when in contact with acids. Reacts violently with potassium hydroxide and sodium hydroxide. Its vapor is heavier than air and can spread to a considerable distance at lower levels. It will ignite and reignite when exposed to a source of fire.
Harmful combustion products:
Carbon monoxide, carbon dioxide.
Fire extinguishing method:
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 has changed color or produced sound from the safety relief device, it must be evacuated immediately. Extinguishing agent: foam, carbon dioxide, dry powder, sand. Using water to extinguish the fire is ineffective.
Emergency response to leakage
Emergency Management:
Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Enter the site from the upwind direction. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Absorb or absorb with sand or other non combustible materials. You can also rinse with a large amount of water, dilute the washing water, and put it into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Cover with foam to reduce steam disaster. Spray like water cools and dilutes steam, protects on-site personnel, and dilutes leakage into incombustible materials. Transfer to a tanker or dedicated collector using an explosion-proof pump, and recycle or transport to a waste disposal site for disposal.
