Tetrahydrofuran

Zhejiang Realsun Chemical Co., Ltd. is one of the most reliable manufacturers and suppliers of tetrahydrofuran in China. If you're going to buy high quality tetrahydrofuran, welcome to get pricelist and free sample from our factory. Good service and low price are available.

 

Liansheng currently manufactures industrial-grade Tetrahydrofuran (THF). The company does not operate dedicated production lines for electronic-grade or pharmaceutical-grade THF.
The product is recovered and purified from the company's PBS/PBAT biodegradable polyester production process. Continuous distillation is used to remove water and control peroxide levels and other impurities.
For semiconductor wafer processing or high-end pharmaceutical applications requiring ultra-high-purity anhydrous THF, small customized distillation samples may be available for laboratory evaluation. Long-term bulk supply of these ultra-high-purity grades is currently not available.

THF is a versatile polar ether solvent with broad solvency for polymers, organic compounds and organometallic reagents.
It is widely suited to industrial applications involving polyurethane, pharmaceutical synthesis, PVC coatings and polymer processing.
Liansheng's industrial-grade THF is positioned for commercial production applications requiring stable purity and controlled water and peroxide levels.

 

 

Each commercial batch is supplied with a batch-specific GC-based COA.

2. Pharmaceutical & Fine Chemical Synthesis
THF is widely used as a reaction solvent in fine chemical synthesis.
Typical applications include:
• Grignard reagent reactions
• Organolithium chemistry
• Heterocyclic pharmaceutical intermediate synthesis
• Antiviral pharmaceutical intermediate production
• Extraction and purification of selected pharmaceutical intermediates
Common Purchasing Challenge
Low-quality THF may contain excessive water or peroxide levels, which can interfere with sensitive chemical reactions and increase the risk of unwanted impurities.
Liansheng controls these two key parameters through continuous purification, supporting direct use in applicable industrial synthesis processes without additional dehydration or purification under normal requirements.
Customers with specific pharmaceutical specifications should provide their internal requirements for technical evaluation before qualification.

 

3. Coatings & Adhesives
THF provides high solvency for a range of resin systems and can be used in:
• PVC inks
• Epoxy industrial adhesives
• Synthetic leather coatings
• Resin-based coating systems
• Solvent-based formulations
Its solvency and evaporation characteristics make it suitable for applications requiring effective resin dissolution and controlled film formation.
Common Purchasing Challenge
Certain aromatic solvents may face additional regulatory and export considerations, while conventional ester solvents may not provide sufficient solvency for some resin systems.
THF offers strong resin solvency for applicable industrial formulations.

 

 

1. Production Capacity
The THF supply is supported by a 2,357-ton/year recovery capacity associated with the company's PBS/PBAT biodegradable polyester production facility.
The recovery process is integrated with the site's BDO production chain and does not rely on externally purchased crude THF as the primary feedstock.
2. Inventory Availability
Dedicated explosion-proof, temperature-controlled storage tanks are used for product storage.
Safety inventory is maintained to support different purchasing requirements, including:
• 20 kg R&D samples
• 200 kg drum orders
• 1,000 kg IBC orders
• Full-container-volume purchases
3. Order Options
Liansheng supports:
• 20 kg R&D samples
• Full-container orders
• 1–3 year annual framework agreements
• Long-term price-lock arrangements
Credit qualification and payment terms can be reviewed for overseas customers.
Written delivery commitments can also be discussed for qualified long-term customers.
4. Delivery Lead Time
Domestic stock can generally be dispatched within 3 days.
For export container orders, hazardous chemical declaration and customs procedures can generally be completed within 7–10 days, subject to order quantity, documentation and shipping schedules.
Shipments can be arranged from Chinese ports to major destinations in Europe, North America, Southeast Asia and Northeast Asia.

 

 

Standard Export Packaging
 R&D Samples
• 25 L HDPE light-protected plastic drums
• 20 kg per drum
• Double-layer leak-resistant inner liner
• Sealed packaging
 Standard Export Orders
• 210 L heavy-duty corrosion-resistant plastic drums
• Net weight: 170 kg per drum
• Solvent-resistant sealing gasket
 Large-Volume Orders
• 1,000 kg sealed IBC containers
• Insulated ISO tank containers available for suitable bulk orders

 

 

Sealed Packaging
Export packaging is designed to limit exposure to air and light.
This helps reduce the risk of peroxide formation during storage and transportation.
Under normal ocean transportation conditions of approximately 45 days, the sealed packaging is designed to maintain stable water content and purity when properly handled.

Hazardous Chemical Transportation
THF is classified as UN 2056, Class 3 flammable liquid.
Liansheng maintains a dedicated hazardous chemical export team to support the required shipping and maritime documentation.

Transportation Options
Available transportation solutions include:
• Full-container-load ocean freight
• LCL ocean freight
• Air freight for samples
Hazardous cargo transportation can be arranged with the applicable insurance coverage.

Storage
Store in a cool, explosion-proof and tightly sealed warehouse.
The storage environment should minimize exposure to light and air.
Peroxide levels are monitored periodically to support safe storage and product quality control.

For quotation and technical evaluation, overseas buyers are recommended to provide:
• Required purity
• Application
• Estimated annual demand
• Order quantity
• Packaging requirements
• Destination country
• Required quality documentation
• Internal water or peroxide specifications, if applicable
For pharmaceutical and specialty chemical applications, customers can provide their internal specifications for technical review before commercial qualification.
