99.9% Purity colorless liquid 1 4 Butanediol BDO CAS 110-63-4

Product Detail of BDO:

1,4-Butanediol (BDO) is a non-corrosive, colorless, high-boiling liquid with low toxicity. BDO is completely soluble in water, most alcohols, esters, ketones, glycol ethers and acetates, but may be immiscible or partially miscible with common aliphatic and aromatic/chlorinated hydrocarbons. BDO is produced from propylene oxide by Lyondell Chemical Company through a proprietary multi-step reaction. BDO is a versatile chemical intermediate because of its terminal primary hydroxyl group and its hydrophobicity and chemical resistance.

Application field of 1,4- butanediol:

(1). 1, 4-butanediol is the main material for producing polyurethane artificial leather, polyurethane, elastomer and polyurethane sole glue. Polyurethane elastomer are widely used to manufacture elastic sole, auto solid fire, friction conveying belt and etc.
(2). 1, 4-butanediol is the main raw material for producing THF, which is an important organic solvent. The polymeric compound PTMEG of THF forms the basic material for highly-elastic urethane elastic fiber, which is mainly used for producing high-grade sports wear and swimming suit that requirs high elasticity.
(3). 1, 4-butanediol is the main material for producing &gamma; -butyrolacton, which is widely used in pesticide, pharmaceuticals, cosmetics and other industries due to its ability to produce NMP and their derivatives NVP and PVP etc. High add-ons products.
(4). 1, 4-butanediol is an important raw materials for organic and refined. It is the basic material for producing PBT plastics and fiber, and PBT is one of the five most promising engineering plastics.

1,4-Butanediol uses include cleaning compounds, cosmetics, eye liner, eye shadow, ink, plasticizer, polyester polymers, polyurethanes, solvent, THF, and urethane polymers.

Polyurethanes: 1,4-Butanediol is used in both the hard and soft segments. In the hard segment as a chain extender and in the soft segment as polyesterdiols such as polybutylene adipate glycol. In addition to its use in the soft segments of polyurethanes, 1,4 BDO is used in the hard segments of some polyurethanes, particularly those made with MDI or TDI. In the hard segment or as a crosslinker, 1,4 BDO produces a good balance between hardness and low temperature flexibility

Esters: These esters include monomeric plasticizers, the engineering plastic polybutylene terephthalate (PBT) and low molecular weight polyester glycols. The polyester glycols are used as soft segments in polyurethanes and are made by reacting 1,4 BDO with various dibasic acids such as adipic and sebacic acid.

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-Butanediol's 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).
