1 4 butandiol (1 4 BD) is a colorless, viscous liquid derived from butan by placement of alcohol groups at each end of its molecular chain and is one of four stable isomers of butandiol.the hydroxyl function of each end group of the Butandiol reacts with different mono- and bifunctional reagents: for example with dicarboxylic acids to polyesters, with diisocyanates to polyurethanes, or with phosgene to polycarbonates. 1 4 Butandiol (BDO) is a high-quality intermediate. BDO and its derivatives are widely used for producing plastics, solvents, electronic chemicals and elastic fibers. Additionally BDO is also a building block for the synthesis of polyesterpolyols and polyetherpolyols. BAS is the most significant producer of 1 4 Butandiol and its derivatives worldwide.


Uses:

  1. Butandiol and its derivatives is used in a broad spectrum of applications in the chemical industry; amongst others in the manufacturing of technical plastics, polyurethanes, solvents, electronic chemicals and elastic fibres.

  2. 1 4 Butandiol is used in the synthesis of epothilones, a new class of cancer drugs. Also used in the stereoselective synthesis of (-)-Brevisamide.

  3. 1 4 Butandiol's largest use is within tetrahydrofura (THF) production, used to make polytetramethylene ether glycol, which goes mainly into spandex fibers, urethane elastomers, and copolyester ethers.

  4. It is commonly used as a solvent in the chemical industry to manufacture gamma-butyrolacton and elastic fibers like spandex.

  5. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings.

  6. It undergoes dehydration in the presence of phosphori acid yielded teterahydrofuran, which is an important solvent used for various applications.

  7. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU).

  8. It finds application as an industrial cleaner and a glue remover.

  9. 1 4 butandiol is also used as a plasticiser (e.g. in polyesters and cellulosics), as a carrier solvent in printing ink, a cleaning agent, an adhesive (in leather, plastics, polyester laminates and polyurethane footwear), in agricultural and veterinary chemicals and in coatings (in paints, varnishes and films).
