【 Use 3 】
1, 4-butanediol is widely used. In the United States and Western Europe, more than half of it is used in the production of tetrahydrofuran, followed by the production of γ-butyrolactone and polybutylene terephthalate, which is a rapidly developing engineering plastic; 1, 4-butanediol is used as chain extender and polyester raw material in the production of polyurethane elastomers and soft polyurethane foams. The esters obtained from 1, 4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylate and polyester. 1, 4-butanediol has good hygroscopic flexibility and can be used as a gelatin softener and water absorbent, as a treatment agent for cellophane and other non-paper. N-methylpyrrolidone, n-vinylpyrrolidone and other pyrrolidone derivatives are also used in the preparation of vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softeners, adhesives and brighteners for the electroplating industry.
【 Use 4 】
The solvent. Wetting agent. Intermediate of plasticizer. A crosslinking agent for the manufacture of polyurethane elastomers. Organic synthesis. To make tetrahydrofuran.

Storage condition
Store in a cool, ventilated warehouse, away from fire. Keep containers sealed, stored away from oxidants, and away from water sources. Emergency spill treatment equipment and suitable containment materials should be available. It can be stored in sealed containers made of mild steel, aluminum or copper.

It is packed in aluminum, stainless steel, galvanized iron or plastic drums, or stored and transported by tank truck according to flammable and toxic substances. Because the melting point is as high as 20 ° C, the tank car should be equipped with heating pipes.
Stability does not decompose at normal temperature and pressure. Avoid contact with oxide and moisture. It is hygroscopic and does not corrode metal. Combustible, low toxicity. Toxic. When attached to the diseased or injured skin or consumed, it initially exhibits anaesthetic effects, causing specific pathological changes in the liver and kidneys, followed by sudden death (without prolonged latency) due to central nervous paralysis. Mice oral LD50210 ~ 420mg/kg. Production equipment should be sealed to prevent leakage, and operators should wear protective equipment. Persons with skin wounds are strictly prohibited from contact with this product.
