1,4 BUTANEDIOL (1,4 BDO)

>> 1,4 BUTANEDIOL (1,4 BDO) Process : Davy Mckee (KPT) 1,4-Butanediol(also known as its less popular chemical synonyms:1,4-butylene glycol, 1,4- tetramethylene glycol and 1,4-dihydroxybutane ) is a low-viscosity glycol used almost exclusively as an intermediate to synthesize other chemicals and polymers. The butanediol molecule maintains its original chemical identity only when used as as a solvent. Since butanediol can undergo the typical reactions of a primary alcohol, it lends itself to a very large number of chemical modifications. As it is a difunctional molecule, most of its use is in the area of polymers, such as polyurethanes(prepolymers, cast elastomers, thermoplastic elastomers, reaction injection molding, and fibers such as spandex), polybutylene terephthalate(PBT), a large family of homopolymers and copolymers of N- vinyl-2-pyrrolidone, and copolyester-ether thermoplastic elastomer(COPE).
