Chemical & Physical Properties

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.
