Product Uses


1. 1, 4-Butanediol is an important organic chemical and chemical raw materials. It is the basic raw materials for the production of polyethylene terephthalate (PBT) fiber and PBT engineering plastic, which is one of the five most promising engineering plastics.
2. 1, 4-Butanediol is the main raw material for the production of tetrahydrofuran (THF), which is an important organic solvent and whose polymerization product poly tetramethylene ether glycol (PTMEG) is the basic raw material for the production of high elastic spandex which is mainly used for the production of senior sports suits and swimming suits.
3. 1, 4-Butanediol is the main raw material for the production of γ-butyrolactone, which is mainly used for the production of α-pyrrolidone and N-methyl-2-pyrrolidinone (NMP). Their derivatives such as N-vinyl pyrrolidone and polyvinyl pyrrolidone are a series of high value-added products and are widely used in the production of pesticides, pharmaceuticals, and cosmetics.
4. 1, 4-Butanediol is an important raw material for the production of polyurethane leather, polyurethane elastomer rubber, and polyurethane soles. Polyurethane elastomer is widely used in the production of soles, solid tires and drive belts.

Toxicity and protection


Poisonous. When drunk on a patient or injured skin, the initial anesthetic effect can lead to a specific pathological change in the liver or kidney, and then a sudden death due to central nervous paralysis. The production equipment should be sealed to prevent leakage and the operators wear protective gear. Contact with this product is strictly prohibited in the skin.

Packaging, Storage, and Transportation

1, 4-Butanediol should be packaged in 200-liter nitrogen-sealed steel drums which adopt GB/T325.1 standards and ISO tank.
It must maintain its temperature not below 20℃ during storage and transportation which can avoid crystallization and be good for loading and unloading.
When transported, it should prevent sun-scorched and rain-drenched and be far away from the fire sources, heat sources and hot gases zone.
