BDO (1,4-butylene glycol)→PBS(poly butylene suecinate):BDO is an important basic organic chemical material. 1.4-Butanediol is a fine chemical material with extensive application. BDO’s derivatives are fine chemical products with high added value. 1.4-Butanediols are widely used in solvent, pharmaceutical, polyurethane, fiber, engineering plastics, cosmetics, plasticizer, hardening agent, pesticide and etc.


The hydroxyl function of each end group of the Butanediol reacts with different mono- and bifunctional reagents: For example with dicarboxylic acids to polyesters, with diisocyanates to polyurethanes, or with phosgene to polycarbonates.

Additionally 1.4-Butanediol is also a building block for the synthesis of polyesterpolyols.

BDO (1.4-Butanediol) is Now Mainly Used to Produce:

Tetrahydrofuran (THF)

Polytetrahydrofuran (PTMEG)

γ-butyrolactone (GBL)

Polybutylene terephthalate (PBT)

Biodegradable resin (PBS)

Polyurethane (PU)

N-methyl pyrrolidone (NMP)

Poly(butylene adipate-co-terephthalate) (PBAT)
