Use

Butanediol 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. 1,4-Butanediol is used in the synthesis of epothilones, a new class of cancer drugs. Also used in the stereoselective synthesis of (-)-Brevisamide. 1,4-Butanediols largest use is within tetrahydrofuran (THF) production, used to make polytetramethylene ether glycol, which goes mainly into spandex fibers, urethane elastomers, and copolyester ethers. It is commonly used as a solvent in the chemical industry to manufacture gamma-butyrolactone and elastic fibers like spandex. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings. It undergoes dehydration in the presence of phosphoric acid yielded teterahydrofuran, which is an important solvent used for various applications. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU). It finds application as an industrial cleaner and a glue remover. 1,4-butanediol 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).
