99.9% Purity colorless liquid CAS 110-63-4 1,4-Butylene glycol BDO
Product Detail of 1,4-Butylene glycol:
1,4-Butylene glycol(1,4-Butanediol) is a non-corrosive, colorless, high-boiling, low-toxicity liquid.
BDO is fully 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 Leondale
Chemical Company through a proprietary multi-step reaction. BDO is
a versatile chemical intermediate due to its terminal primary
hydroxyl groups as well as its hydrophobicity and chemical
resistance.

Application field of 1,4-Butylene glycol:
(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 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
plastics.
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.
