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

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
(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 γ
-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
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
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
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
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).
