1,4-Butanediol (BDO) CAS 110-63-4 Purity ≥99.5% (GC) Factory

1,4-Butanediol (BDO) (CAS: 110-63-4) is an important organic chemical and fine chemical raw materials, high quality intermediate. It is the production of Polybutylene Terephthalate (PBT) basic materials engineering plastics and PBT fibers, and PBT plastic is the most promising one of the five major engineering plastics. 1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes.
1,4-Butanediol is derived from butane by placement of alcohol groups at each end of its molecular chain and is one of four stable isomers of butanediol.the hydroxyl function of each end group of the Butanediol 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-Butanediol 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.
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.
1,4-Butanediol 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.
1,4-Butanediol undergoes dehydration in the presence of phosphoric acid yielded teterahydrofuran, which is an important solvent used for various applications.
1,4-Butanediol acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU).
1,4-Butanediol 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).
Air & Water Reactions Highly flammable. 1,4-Butanediol is hygroscopic. Water soluble.
Reactivity Profile 1,4-Butanediol is heat and light sensitive. 1,4-Butanediol reacts with acid chlorides, acid anhydrides and chloroformates; reacts with oxidizing agents and reducing agents. 1,4-Butanediol is incompatible with isocyanates and acids; also incompatible with peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide and chlorine.
Hazard Toxic by ingestion.
Health Hazard The acute toxic effects are mild. 1,4-Butanediolis less toxic than its unsaturate analogs,butenediol and the butynediol. The oralLD50 value in white rats and guinea pigsis ~2 mL/kg. The toxic symptoms fromingestion may include excitement, depressionof the central nervous system, nausea, anddrowsiness.
Health Hazard Ingestion of large amounts needed to produce any symptoms.
Fire Hazard Nonflammable liquid, flash point (open cup) 121℃.
Safety Profile A human poison by an unspecified route. Moderately toxic byingestion and intraperitoneal routes. Human systemic effects: altered sleep time. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, mist, foam, CO2, dry chemical. Incompatible with oxidizing materials. When heated to decomposition it emits acrid smoke and fumes.
