1.4-Butanediol (BDO)


1.4-Butanediol (BDO) Instruction:

1,4-Butanediol (BDO) is an organic substance with molecular formula C4H10O2 and molecular weight 90.12. Appearance is colorless or light yellow oily liquid. Flammable, freezing point 20.1℃, refractive index 1.4461. soluble in methanol, ethanol, acetone, slightly soluble in ether. 1.4-Butanediol (BDO) is hygroscopic and has a bitter taste, but slightly sweet in the mouth. Used as solvent and humidifier, also used as plasticizer, drug, polyester resin, polyurethane resin, etc.


1.4-Butanediol (BDO) Applications:

1,4 Butanediol is an important organic chemical and fine chemical raw material, and is the basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fiber; PBT plastic is one of the five most promising engineering plastics.
1,4 butanediol is the main raw material for the production of tetrahydrofuran, which is an important organic solvent. The polytetramethylene glycol ether (PTMEG) obtained after polymerization is the basic raw material for the production of high-elasticity spandex (Lycra fiber). Spandex is mainly used in the production of high-elasticity knitted products such as advanced sportswear and swimwear.
γ-butyrolactone, a downstream product of 1,4-butanediol, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone, from which a series of high value-added products such as vinylpyrrolidone and polyvinylpyrrolidone are derived, which are widely used in the fields of pesticide, medicine and cosmetics.

Packed in aluminum, stainless steel, galvanized iron barrels or plastic barrels, or stored and transported in tanker trucks according to the provisions of flammable and toxic substances. Because the melting point is as high as 20℃, the tanker should be equipped with heating pipes.
