Update time:2021/11/05 13:14:11  ???View:  
1,4-Butanediol (abbreviated as BDO) is an important organic and fine chemical raw material, it is widely used in the fields of medicine, chemical industry, textile, papermaking, automobile and daily chemical industry. BDO can produce tetrahydrofuran (THF), polybutylene terephthalate (PBT), gamma-butyrolactone (GBL) and polyurethane resin (PU Resin), coatings and plasticizers, etc., as well as solvents and electroplating Brighteners in the industry, etc.
 
Nature
Colorless viscous oily liquid. It is flammable, with a freezing point of 20.1°C and a refractive index of 1.4461. It is soluble in methanol, ethanol, acetone, and slightly soluble in ether. It is hygroscopic, has a bitter odor, and has a slightly sweet taste in the mouth.
 
Use
1,4 Butanediol is an important organic chemical and fine chemical raw material, and it is the basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fibers; PBT plastics are the five most promising ones. One of engineering plastics.
1,4-Butanediol is the main raw material for the production of tetrahydrofuran, which is an important organic solvent. Polytetramethylene glycol ether (PTMEG) obtained after polymerization is the basic raw material for the production of highly elastic spandex (Lycra fiber). Spandex is mainly used to produce high-elastic knitwear such as high-grade sportswear and swimming suits.
The downstream product of 1,4-butanediol, γ-butyrolactone, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone products, from which a series of high value-added products such as vinylpyrrolidone and polyvinylpyrrolidone are derived. It is widely used in the fields of pesticides, medicine and cosmetics.
